Experimental and Theoretical Studies for Morphology Evolution of Immiscible Polymer Blend in a Twin Screw Extruder

Abstract

Recently, plastic problems related to global warming and ocean pollution have become serious social problems. In order to confront the plastic problems, efforts are being made world widely to develop various technologies aimed at realizing recycling-oriented society. The use of naturally derived polymer material such as CA (Cellulose Acetate) is expected to be an effective way to solve the plastic problems. In the present research, a simulation technology for predicting the morphology of CA/PVA (Polyvinyl Alcohol) polymer blend formed in a twin screw extruder is proposed. The effectiveness of the technology was verified by comparing with the experimental data collected under various operating conditions of a twin screw extruder.
