MODIFIED SYNTHETIC CONDENSATION POLYMERS AND THEIR PRODUCTION
A method is proposed for modifying the properties of condensation polymers by inducing graft copolymerization bv irradiation while in intimate contact with an unsaturated acid of low molecular weight or one of its derivatives. Suitable unsaturated acids are crotonic, furoic, acrylic, maleic, dichloromaleic, fumaric, and itaconic and substituted derivatives thereof. The grafted structures usually contain free carboxyl or carboxylate metal salt groups; carboxyl groups may be converted into carboxylate salt groups by soaking the graft polymer in a solution of a basic metal salt. Examples are given in which nylon is saturated with maleic anhydride solution or a solution of maleic anhydride and methoxydecaethyleneoxy methacrylate monomer, wrung out, and irradiated. (D.L.C.)
