Polyacrylate materials

Abstract

A composition comprising: (1) 0.1 to 84.0 wt % of a polymeric resin selected from PVC homopolymers, PVC copolymers, CPVC, PLA, SAN, ASA, CPE, EVA, ABS, MBS, polycarbonate, conventional acrylic ester polymers or mixtures thereof; and (2) 16.0 to 99.9 wt % of a polyacrylate resin/material (PAM) composition comprising a polymer (A) phase and a polymer (B) phase present in a ratio of polymer (A) phase/polymer (B) phase of 50/50 to 90/10, polymer (A), having a glass transition temperature Tg below −40° C., comprising 95.0 to 99.5 wt % of a first polymeric component (A1) of one or more mono-ethylenically unsaturated monomers selected from the group consisting of alkyl acrylates having an alkyl group containing from 1 to 8 carbons, and 0.5 to 5.0 wt % of a second polymeric component (A2) of one or more polyethylenically unsaturated monomers, where the double bonds can be of the same or differing reactivity; and polymer (B), having a glass transition temperature Tg above 85° C., comprising a first polymeric component (B1) of one or more monoethylenically unsaturated monomers selected from the group consisting of alkyl methacrylates having an alkyl group containing from 1 to 4 carbons, and optionally, 1.0 to 10.0 wt % of other monomers, based on the total weight of the (B1) component, selected from alkyl acrylates, vinylbenzene or substituted vinylbenzenes or mixtures thereof, and optionally a second polymeric component (B2) comprising 0.3 to 2.5 wt % based on the total weight of polymer (B) of one or more polyethylenically unsaturated monomers where the unsaturated bonds can be of the same or differing reactivity.
