摘要：

Random vinyl ketone copolymers were found to degraded more efficiently than blends of polystyrene with vinyl ketone copolymer concentrates containing the same molar ketone content. The blends were prepared from polystyrene and styrene-co-methyl vinyl ketone (SMVK) resins containing from 0..25-10 mol% ketone or ECOLYTE(TM) polystyrene. Foam food packages and films were prepared as test specimens for this study. Both outdoor (Southern Florida) and indoor (QUV) weathering test were conducted.
