Abstract

1,166,799. Block copolymer-bitumen compositions. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 7 Aug., 1968, No. 37702/68. Heading C3P. A thermoplastic elastomeric composition comprises (a) a block copolymer of the formula A-B-A where each A is a polymer block of a monoalkenyl aromatic hydrocarbon and B is a polymer block of a conjugated diene hydrocarbon, the average molecular weights of the A blocks being 2000 to 100,000 and those of the B block being 25,000 to 500,000, (b) an aromatic asphaltic bitumen having a ratio of carbon atoms to hydrogen atoms in the range of 0.60 to 1.25 and a penetration index of at most zero, the amount of bitumen being 5 to 50% of the weight of the block copolymer-bitumen mixture, and optionally (c) fillers (reinforcing such as carbon black, and non-reinforcing such as whiting), antioxidants, antiozonants and extender oils which are naphthenic, aromatic or polymeric. In the examples poly(styrene-6-butadiene-bstyrene) is mixed with various commercial aromatic asphaltic bitumens, naphthenic and aromatic extending oils, whiting, styrenebutadiene random copolymer, and polystyrene.
