High-notched-impact core-shell polymers having improved weather resistance

TLDR
A particulate graft polymer is a core formed by a crosslinked homopolymer of a conjugated diene or a copolymer thereof with up to 10% by weight of styrene or acrylonitrile.
Abstract
A particulate graft polymer comprising (a) a core formed by a crosslinked homopolymer of a conjugated diene or a copolymer thereof with up to 10% by weight of styrene or acrylonitrile; (b) a first shell formed by a crosslinked homopolymer of an acrylic acid alkyl ester or a copolymer thereof with up to 30% by weight of vinyl monomers; (c) a second shell formed by a polymer of resin-forming monomers, a process for manufacturing these graft polymers by means of a multi-stage emulsion polymerization, and their application as molding compositions, optionally together with rigid thermoplastic resins.
