This article investigated the effects of electron beam (EB) irradiation on poly(D,L-lactic acid)-b-poly-(ethylene glycol) copolymer (PLEG) and poly(L-lactic acid) (PLLA). The dominant effect of EB irradiation on both PLEG and PLLA was chain scission. With increasing dose, recombination reactions or
