Acrylate material comprising sequentially polymerized four composition particle having radially graduated transitional properties

摘要: A four composition acrylate particle optimizes sequence formulations: (1) beginning with a cross-linked elastomer core upon which (2) successive layer of principal quantity elastomer, includes graft-linking component, is polymerized, in turn (3) protectively encapsulated by successively polymerized shell, also and coated (4) final transition coating. The chemically bonded into unit provides radially graduated between the significantly different properties coating adapted to matrix system particles may be blended.
