Abstract

Abstract Vinyl halide resin compositions that are resistant to attack by fungi and bacteria contain 0.01 to 2 percent by weight of a compound having the structural formula WHEREIN X and X'' each represents hydrogen or halogen; Y and Y'' each represents alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen, nitro, or benzyl; Z represents alkyl of 1 to 4 carbon atoms, halogen, or nitro; and m represents a number in the range of 0 to 3. Illustrative of these compounds are N2,6-diisopropylphenylmaleimide and N-(2-methyl-6chlorophenyl)maleimide.
