Abstract
Abstract A mixture useful for the manufacture of shaped bodies and as a molding composition which comprises a bituminous crude oil vacuum residue having a density under 1,000 g/ml at 25*C., a viscosity of 10*-30*E. at 90*C., a drip point according to Ubbelohde of 30*-50*C., a Cleveland flame point of above 250*C. or a bituminous gas oil having a density of less than 0.980 g/ml and a viscosity of 5*-50*E. at 50*C. and an amorphous polyolefin, the combined content of the bituminous product and polyolefin being between 5 and 95% by weight based on the weight of the mixture.
