CHE 360: POLYMER CHEMISTRY SYLLABUS Instructor: Dr. Zachary Rodgers Text: Introduction to Polymer Chemistry (Carraher) Course webpage: Desire2Learn Prerequisites: CHE 262: Organic Chemistry Contact Info: (724)-946-6289 [email protected] Class Time: TR 9:10 – 10:50 am Lab Time: R 2:00 – 5:00 pm Course Overview The word polymer comes from the Greek words “poly”, meaning many, and “mer”, meaning parts. Like the macrostructures we see every day, such as a house built of brick, the larger structures of polymers have very different properties from their smaller chemical building blocks. The uniqueness of polymer properties provide most of the materials we interact with on a regular basis, including our clothes, plastics, paper, adhesives, and even our bodies themselves. Therefore, no education in chemistry would be complete without describing the general properties, synthesis, processing, and function of polymeric materials. This semester long course aims to: Describe how polymer morphology affects a polymer’s overall properties and behavior Teach polymer characterization techniques to determine their structure and size Detail a variety of polymerization mechanisms and their underlying kinetic/thermodynamic characteristics Introduce the practical techniques used to synthesize a wide range of polymeric structures Provide several examples of the industrial processing techniques used to generate consumable polymer products Make connections between material to answer complex and multi-step problems Expose students to literature research in materials and polymer science Grading Grading Weights 10% Homework Assignments (~6 – 8 total) 20% Laboratory Grade 37.5% Exams (3 Tests) 12.5% Student Presentation 20% Final Grading Scale 90 - 100 A 72 – 77 C 88 - 89 B+ 70 – 71 C- 82 – 87 B 68 – 69 D+ 80 – 81 B- 60 – 67 D 78 – 79 C+ < 60 F The scale set in this syllabus is non-negotiable. Homework Assignments: I will provide homework assignments at regular intervals (2-3 per test cycle) to help you study and practice for your exams. Most homeworks will consist of short answer questions ranging from simple to more challenging, critical thinking problems. These assessments will be graded for completeness and correctness. You are allowed to work with classmates on these if you wish. Laboratory Grade: We will have lab each week, but not every period will have a new lab. Some lab periods will provide time to catch up on characterization and data analysis. Each lab assignment will require a written pre-lab that counts as ~20% of your lab score. The rest of your lab grade will vary for each lab assignment’s goal and assessment, but they may include a lab report, analyzing an unknown and determining its property or nature, or demonstrating aptitude for a particular technique. Each lab handout will have the assessment’s grading criteria clearly outlined and described. Exams: Tests will examine your deeper comprehension of the covered material. These exams may include multiple choice, short answer, mechanism schemes, synthesis, etc. These will be administered roughly once a month on the days indicated. Student Presentation: At the end of the semester, students must give a presentation (using PowerPoint) on at least two related and recently published papers dealing with some aspect of polymer chemistry. These papers must come from peer-reviewed chemistry or engineering journals and contain original research (no reviews). Students will work in groups of two for this assignment and may pick any polymer topic they find interesting. Papers must be selected by the students and approved by me at least a month prior the scheduled presentation (see below). A rubric detailing how the grade assignment will work for this presentation will be provided before students begin selecting potential manuscripts. Final: This is a comprehensive final and will be structured as a longer test. Additional Resources Online Resources: I will post additional resource material, such as mechanism videos, molecular models, and practice problems, on the course Desire2Learn website for you to review. I encourage all of you to suggest problems that you are struggling with so that I may tailor these resources for class needs. Office Hours: Monday 2:00 p.m. – 3:00 pm Tuesday 11:00 a.m. – 12:00 pm Thursday 11:00 a.m. – 12:00 pm Friday 9:30 a.m. – 10:30 a.m. I am also available for office hours by email appointment (my brain needs it in writing) provided you allow for several days’ notice. Please bring specific questions or concerns to make these sessions more productive. Form a study group: Most of you are upper-level students who have interacted with one another throughout your time at Westminster. Therefore, you should find it easy to get to know one another better and work together on homework and exam prep. However, if you do not know anyone in class, let me know and I will assist you in finding peers to study with. Be sure to have others assess your understanding of the material prior to each test. Tips to Succeed Read, read, READ: The suggested reading sections will prepare you for lecture so that you can absorb more of the information and gain a deeper understanding of the material. Study together: If you wish, I will help you find other students to study with. Making friends while aiding each other in learning will make the class more enjoyable and improve your collaboration skills. Set aside time each week to meet with a study group so that you will hold each other accountable for studying. Practice and test your knowledge several times a week using the problems in the text: Set aside time each week (~3- 4 hours) to read/practice and stay ahead of the material. If you do this, you will be able to quickly adapt to new material and have to devote less time (and loss of sleep) to studying during test week. Attendance Class attendance is not mandatory, but I would highly encourage you to attend class when possible so you do not miss anything. However, lab attendance is mandatory. Two unexcused lab absences will result in a F for the course. School sanctioned events (sports, class field trips, band, etc.) and illnesses are excused absences. Please inform me ahead of time about possible absences so that I can provide a make-up time for you. Academic Honesty All students must hold themselves to the highest standards of academic integrity while in the course. Instances of cheating (attempting to gain an unfair advantage on an assignment without prior approval or permission), plagiarism (copying another person’s work), class disruption (creating a poor learning environment for other students), etc. deemed unacceptable by me will result in the following penalties: First Offense: The assignment in which the infraction occurred will be scored at a 0%. No make-up assignment will be provided, and the offense will be reported to the proper departments and administrators at the school. Second Offense: The student will receive an F in the course.
