(CO)POLYMER COAGULATION SEPARATION PROCESS

摘要

The invention relates to a (co)polymer coagulation separation process, using polyvinyl alcohol as a disperser. There can be manufactured by means of this process especially low viscousity block copolymers containing at least a main block of conjungated diene and at least a main aromatic vinyl block. The polyvinyl alcohol consists of an average molecular mass ranging from 200 to 200000 and of a medium hydrolysis degree ranging from 25 to 98%.
