Abstract
Compositions comprising a coupled interpolymer such as polybutadiene which may be suitable for HIPS and ABS have been discovered. The coupled interpolymer composition comprises an interpolymer comprising one or more monomeric units derived from a diene wherein the coupled interpolymer composition is characterized by: (A) a halide content of less than about 30 ppm based on the total weight of the coupled interpolymer; (B) a molecular weight distribution of from about 1.6 to about 2.4; and (C) a vinyl content of from about 5 to about 15 weight percent based on the total weight of the coupled interpolymer.
