Abstract
This invention provides a flame-retardant resin composition comprising (A) about 100 parts by weight of at least one resin selected from the group consisting of ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, isobutylene-isoprene copolymer and ethylene-propylene-diene terpolymer, (B) about 50 to about 300 parts by weight of a hydrate of metallic oxide, and (C) about 0.05 to about 5 parts by weight of a phosphorus-containing titanate coupling agent, the composition having been already crosslinked by use of about 0.1 to about 20 parts by weight of a crosslinking agent or by irradiation of ionizable radiation. The composition of the invention has an outstanding flame retardancy and can be made into a molded product capable of exhibiting fully useful mechanical and electrical characteristics.
