POLYVINYL ALCOHOL FIBER REINFORCED POST-CHLORINATED POLYVINYL CHLORIDE RESINS

摘要

Post-chlorinated vinyl chloride resins including homopolymers of vinyl chloride and copolymers thereof with an olefin such as propylene, having high impact strength together with an adequate melt flow rate are prepared by incorporating polyvinyl alcohol fibers into the resin. The polyvinyl alcohol fibers are completely hydrolyzed, about one-eighth to one-half inch in length, about 1 to 10 denier and have a degree of polymerization in the range of 500 to 3,000.
