Patent ID: 8092722

Claim:
A curable composition comprising: a functionalized poly(phenylene ether), an unsaturated polyester, and/or a vinylester resin; a reactive liquid monomer, and a block copolymer comprising a poly(olefin) block comprising repeat units derived from a C 2 -C 4 olefinic monomer or a poly(diolefin) block comprising repeat units derived from a C 4 -C 6 diolefinic monomer and at least one terminal poly(alkenyl aromatic) block comprising repeat units derived from an alkenyl aromatic monomer; wherein the block copolymer comprises a poly(acrylic) block derived from methacrylic C 1 -C 6 ester monomers and wherein the terminal poly(alkenyl aromatic) block is a poly(styrene) block derived from styrene monomer, each of said poly(acrylic) block and poly(styrene) blocks located at a terminal end of the block copolymer.
