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