METHODS FOR FORMING BLENDS OF POLYOLEFIN AND RESIN MODIFIER

摘要

A process for preparing a blend of thermoplastic polymer and resin modifier within a single- screw extruder, wherein the resin modifier is a hydrocarbon resin. The single-screw extruder is designed to have a screw with a compression ratio of at least 1.2. The compression ratio is the ratio of the screw depth at the feed section (30) to the screw depth at the metering section (34).
