Abstract

1,271,760. Block copolymer-polypropylene composition. SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ N.V. 13 July, 1970 [14 July, 1969], No. 33836/70. Heading C3P. A composition comprises (a) a branched or radial block copolymer of the formula where each A is a polymer of a monoalkenyl aromatic hydrocarbon, each B is a polymer of a conjugated diene, and n is 2 to 5, and (b) 20 to 40 parts per 100 parts of (a) of a polypropylene. A is typically polystyrene or polyalphamethylstyrene, and B is typically polyisoprene or poly butadiene.
