摘要
We have made a study of blending polymer pairs of different viscosity and interfacial tension levels in a modular co-rotating twin screw extruder and examining the phase condition and blend morphology along the screw axis. The polymers studied included polyethylene, polystyrene, polyvinyl acetate and polyethylene glycol. Different screw configurations, mixing elements and feed ports were used in this study.
