Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
40 words
A metal plated poly(aryl ether) containing article, said poly(aryl ether) comprising a blend of a poly(aryl ether) polymer, a styrene copolymer, acrylic copolymer and a compatibilizing in amounts of from about 0.5 to about 20 weight percent of a polyhydroxyether.
Claim 2
Dependent Claim
40 words
A metal plated poly(aryl ether) containing article, said poly(aryl ether) comprising a blend of a poly(aryl ether) polymer, a styrene copolymer, acrylic copolymer and a compatibilizing in amounts of from about 0.5 to about 20 weight percent of a polyhydroxyether.
Claim 3
Dependent Claim
72 words
A composition as defined in claim 1 wherein the poly(aryl ether) has recurring units of the formula: O--E--O--E' wherein E is the residuum of a dihydric phenol and E' is the residuum of a benzenoid compound having inert electron withdrawing groups in at least one of the position ortho and para to the valence bonds and wherein both of said residuum are valently bonded to the ether oxygen through aromatic carbon atoms.
