VERFAHREN ZUR HERSTELLUNG VON PROPYLENPOLYMEREN MIT LANGKETTIGER ENDABZWEIGUNG UND IHRE VERWENDUNG.

摘要

Disclosed is a process for making a normally solid, gel-free, amorphous to predominantly crystalline, propylene polymer material having free-end branches of propylene units and strain hardening elongational viscosity by peroxide decomposition of the propylene polymer material in the substantial absence of oxygen at certain temperatures for certain periods of time, and then deactivating the free radicals in the material.
