Patent ID: 8779044

Claim:
A curable polyamide-filled acrylate copolymer composition comprising A. a polymer blend composition comprising 1. 40 to 90 wt. % of one or more amorphous acrylate copolymers comprising a) at least 50 wt. %, based on the total weight of the amorphous acrylate copolymer, of polymerized units of at least one monomer having the structure Where R 1 is H or C 1 -C 10 alkyl and R 2 is -C 1 -C 12 alkyl, C 1 -C 20 alkoxyalkyl, -C 1 -C 12 cyanoalkyl, or -C 1 -C 12 fluoroalkyl, and b) copolymerized units of a cure site monomer selected from the group consisting of unsaturated carboxylic acids, anhydrides of unsaturated carboxylic acids, unsaturated epoxides, and mixtures of two or more thereof; and 2. 10-60 wt. % of one or more polyamides having a melting peak temperature of at least 160° C.; wherein i) the one or more polyamides are present as a discontinuous phase in the polymer blend composition, ii) the green strength of the polymer blend composition is less than about 2 MPa, as determined in accordance with ASTM D6746-10, and iii) the weight percentages of the one or more amorphous acrylate copolymers and the one or more polyamides are based on the combined weight of the one or more amorphous acrylate copolymers and one or more polyamides in the polymer blend composition; and B. an amine curative.
