The blow molded thermoplastic com (Continued) positions exhibit high strength and flexibility. Methods for forming the thermoplastic compositions are also described. (52) U.S. Cl. Formation methods include dynamic Vulcanization of a CPC .................. C08L 63/00 (2013.01); B32B I/08 composition that includes an impact modifier dispersed (2013.01); B60K 15/031 77 (2013.01); C08L throughout a polyarylene Sulfide. A crosslinking agent is 81/04 (2013.01); Y10T 428/139 (2015.01); combined with the other components of the composition Y10T 428/1352 (2015.01); Y10T 428/1393 following dispersal of the impact modifier. The crosslinking (2015.01) agent reacts with the impact modifier to form crosslinks (58) Field of Classification Search within and among the polymer chains of the impact modifier. CPC ...
