Abstract

Particulate graft polymers composed of a core (a) of cross-linked diene rubber, a first envelope (b) of a cross-linked acrylate rubber, a second envelope (c) of a copolymer of resin-forming monomers and polyallyl monomers having at least three allyl groups in the molecule, and a third envelope (d) of a copolymer or homopolymer of resin forming monomers.
