Photo-degradable shotshell of polyethylene and EVA-CO terpolymer

摘要

A photo-degradable, molded, high strength plastic shotshell component having a degradation composition comprising as its combination of active ingredients linear polyethylene having a melt index of 0.1 to 5. 0 and an ethylene-vinyl acetate-carbon monoxide terpolymer, the ratios by weight of which to said linear polyethylene is approximately 0.115:1 to 0. 261:1 The ethylene-vinyl acetate-carbon monoxide terpolymer in its preferred composition has about 65% by weight of ethylene, 25% by weight of vinyl acetate, and 10% by weight of carbon monoxide.
