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.

Acrylate material comprising sequentially polymerized four composition

A process for the production of a moldable thermoplastic having enhanced resistance to impact, and the resulting product, is disclosed. A cross-linked bulk cast elastomer including a graft-linking agent is produced and is then finely divided and compounded with a catalyzed polymerizing monomer mixture, which may also include a minor proportion of a graft-linking co-monomer. Graft-linking of the elastomer to the resulting polymer occurs in situ; and the mass of the elastomer graft-linked to the polymerizing monomer is then compounded with a moldable matrix polymer and the compounded blend is then extruded through a die.

Production of acrylate impact resistant moldable thermoplastic

A four composition particulate additive for blending with a moldable acrylic matrix resin is described. The particulate additive optimizes four sequenced formulations: (1) beginning with a cross-linked elastomer core upon which (2) a successive layer of the 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 thermoplastic shell, which also includes a graft-linking component, and in turn is coated by (4) a final thermoplastic transition coating which is compatible with the matrix resin. The particle is chemically bonded into a unit and provides a graduated transition between the significantly different properties of the principal elastomer in the particle and the matrix resin with which the particles are blended. The blends produced are particularly useful in glazing and the production of sanitary-ware and other products in which impact resistance is a desired quality.
