Process for coagulation finishing of polymers |
摘要 |
A process for coagulation finishing (co)polymer by using polyvinyl alcohol as dispersant during said coagulation. In particular, low viscosity block copolymers, comprising at least one block of predominantly conjugated diene and at least one block of predominantly monovinyl aromatic monomer, can be successfully finished. The polyvinylalcohol is characterized by a weight average molecular weight of from 200 to 200,000 and by an average degree of hydrolysis of from 25 to 98%.
