ABSTRACT:
The blending of an effective amount of an ethylene/carbon monoxide polymer with an internally plasticized vinyl chloride copolymer improves the low temperature flexibility and color stability during ageing of films made from the resulting blend as compared to films containing the internally plasticized resin in the absence of the ethylene/carbon monoxide polymer.
