ABSTRACT:
Polyvinyl halide-EVOH polymer compositions exhibiting a reduced tendency to stick to metal surfaces, and in particular, to chrome surfaces are described which comprise
(A) at least one vinyl halide polymer;
(B) from 1 to about 40% based on the weight of the vinyl halide polymer, of at least one ethylene-vinyl alcohol copolymer; and
(C) from about 0.01 to about 5 phr of at least one phenolic antioxidant of the formula ##STR1## wherein R.sub.1 is hydrogen, or a hydroxyl or an alkyl group; R.sub.2 is an alkyl, alkoxy or a carboxylic ester group; and R.sub.3 is a hydroxy or an alkyl group.
An improved process for melt blending mixtures comprising vinyl halide polymers and ethylene-vinyl alcohol copolymers on metal-surfaced compounding equipment is described which comprises adding to the mixture prior to melt blending, from about 0.01 to about 5 phr of the phenolic antioxidant described above.
