Abstract
Northwestern's solid-state shear pulverization (S3P) process improves the physical properties of a variety of homopolymers. Enhanced polymer crystallinity, mechanical strength, and oxygen barrier properties are achieved with the method, with results rivaling those obtained with nucleating agents, clays, and fillers. Solid-state shear pulverization (S3P), a continuous process shown not to cause degradation in most cases, has also demonstrated intimate mixing and dispersion of immiscible polymer blends and appears well suited to industrial practice. The process has been tested on a range of homopolymers and operated on pilot-scale equipment.
Applications
o Recycling polymers
o Industry-scale processing of one-component polymers
Advantages
o Significantly enhances polymer crystallinity, mechanical strength, and
oxygen barrier properties
o No need for additive nucleating agents or fillers
