ABSTRACT:
Polysegment copolymers with thermoelastomeric properties are obtained by a process, wherein block polymers of the idealised form S.sub.x -B.sub.y, in which S represents structural units derived from styrene, B represents structural units derived from a conjugated diene and x and y are integers, are reacted with sulphur chlorides.
The products according to the invention are suitable for the production of shoe soles, hoses, industrial rubber articles and particularly hot melt adhesives.
