Methode pour retarder la depolymerisation d'un poly(methacrylate de methyle) sur un polymere de propylene

Retarding depolymerization of poly(methyl methacrylate) grafted onto a propylene polymer

Abstract

Depolymerization during melt processing of poly(methyl methacrylate) that is grafted onto a backbone of propylene polymer material is retarded by adding 0.025 parts to 5.0 parts of a hydroxylamine compound per hundred parts of the graft copolymer. The methyl methacrylate can be copolymerized with another monomer such as methyl acrylate.
