Abstract
A rubbery polymer composition comprising (A) a copolymer consisting of 45 to 79% by weight of butadiene, 20 to 55% by weight of acrylonitrile and 0.1 to 10% by weight of at least one compound selected from the group consisting of amide compounds having the formula (I) shown below and imide compounds having the formula (II) shown below, and (B) a vinyl chloride polymer, the weight proportion of said (A) to said (B) being 95-40 to 5-60. Said composition is resistant to ozone and oil, and moreover, is excellent in heat aging resistance and sour gasoline resistance when used in an oil, in a solvent or in the atmosphere at a high temperature: ##STR1## wherein R.sub.1 and R.sub.2 individually represent hydrogen, chlorine, bromine, or alkyl having 1 to 12 carbon atoms; R.sub.3 represents hydrogen, or alkyl having 1 to 4 carbon atoms; and R.sub.4 represents hydrogen, alkyl having 1 to 4 carbon atoms, or aryl having 6 to 12 carbon atoms, ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 are as defined above, and two R's may be the same or different.
