ABSTRACT:
Impact resistance of PVC is shown to be improved by blending therewith polymers derived from monomer systems comprised of at least about 80 percent by weight ethylene oxide. Polymers of at least about 80 percent ethylene oxide and about 0.1 to 2 percent of a symmetrical diepoxide as crosslinking agent are also disclosed.
