FREMGANGSMAATE TIL FREMSTILLING AV POLYMERBLANDINGER FRA POLYMERER MED FORSKJELLIGE MOLEKYLVEKTER

摘要

A process is provided for melt blending polymers comprising mixing a high molecular weight polymer and a low molecular weight polymer in two stages. The two stage process extends the range of the molecular weight of polymers which can be employed and the range of the ratio of the compositions that can be effectively blended.
