Patent ID: 8541515

Claim:
A polymer composition having improved surface properties, the composition comprising: a) a thermoset resin polymer; and b) at least one melt processable, organo-modified siloxane additive capable of reducing the COF of the polymer composition of the formula: R—SiR 1 2 —[O—SiR 1 R 2 ] x —[O—SiR 1 Z] y —O—SiR 1 2 —R in which Z is a radical with the structure —[O—SiR 1 R 2 ] n —O—SiR 1 2 —R R is a hydroxyl or methyl radical; R 1 is a methyl radical; R 2 is selected from the group consisting of a C1 or a C12-C75 saturated or unsaturated, hydrocarbon radical; x is greater than 15; y is 0-50; and n is 0-50 wherein at least 10% of the siloxane units present in the additive compound are not di-methyl siloxanes, and wherein the remainder of the siloxane units are di-methyl siloxanes.
