A Polymer Composition and a method for Retarding depolymerization of (Poly) by grafting Methyl methacrylate was Polymerized in a Skeleton s of propylene Polymer MaterialAnd by forming Said composition

摘要

A Polymer composition comprising (1) a polymeric material comprising a Graft Copolymer comprising a Skeleton of a materialpolu00edmero propylene is Polymerized by injerTo the Poly (methyl methacrylate) or uncopolu00edmero methylmethacrylate and at least a comonomer, where the total amount of Polymerized monomer is approx. Approximately 10 Parts.120 parts per Hundred parts of propylene Polymer Material and elcomonomero, when present, is found in a quantity of up to approx.20 mol% of the total monomers Polymerized, and (2) aprox.0025 Parts approximately.5.0 parts of a hydroxylamine compound that has the formula t1t2noh where T1 is a grupoalquilo C1 - C5 - 36, a grupocicloalquilo 12A Group aralquilo C7 - 9 or aralquilo Group replaced by a c1-4 alkyl group or one or two Atoms of hydrogen and Halogen or T2ES has the same meaning as T1.Ella u00edmero material parts by Pol.A procedure to delay the despolimerizaciu00edonpor Poly (methyl methacrylate) was Polymerized by grafting on a Skeleton of propylene Polymer Material is made by forming dichacompOsition with.
