Preparation of mixtures of high molecular weight polyisobutylene and thermoplastic polymers |
摘要 |
Mixtures of high molecular weight polyisobutylene and thermoplastic polymers are prepared in an extruder by a process in which meterable, high molecular weight polyisobutylene is first metered into the extruder and homogenized in at least one kneading stage, heated and subjected to controlled molecular weight degradation and the thermoplastic polymer is then introduced into the polyisobutylene melt by means of a side feed and is subsequently homogenized together with said melt. The novel process is particularly suitable for the preparation of mixtures of high molecualr weight polyisobutylene and polyethylene.
