Abstract: A homogeneous, high nitrile melt processable acrylonitrile olefinically unsaturated multipolymer and a process for making the multipolymer, comprising polymerizing a mixture of acrylonitrile monomer and one or more olefinically unsaturated monomers, in which the rate of addition of the multimonomer mixture is set by the rate of polymerization so that the concentration of unreacted acrylonitrile monomers and unreacted olefinically unsaturated monomer(s) is low and the polymerization process is in a monomer starved condition.

Abstract: of the disclosure Nitrile copolymers and graft copolymers containing a high proportionate amount of olefinic nitrile are stabilized against thermal color degradation by inclusion into the polymer minor amounts of a compound having the formula: and/or wherein "X" may be oxygen; an imide groups, -NH? or an N-substituted imide group, -NR- wherein "R" may be an alkyl, or a phenyl alkyl group containing from 1 to 8 carbon atoms; "Y" may be an oxygen or a methylene group; and "Z" may be hydrogen or an alkyl group containing from 1 to 8 carbon atoms.
