Improvement Of Mechanical Properties Of Polymers With A Supercritical CO_2 Based Process

摘要

In this work the experimental results of crystallization kinetics of polycarbonate treated with supercritical carbon dioxide at pressure of 170 and 300 bar and at temperature of 60 and 80°C in a batch type reactor are reported and discussed. Mechanical properties polycarbonate samples treated with carbon dioxide under different experimental conditions have been measured and the influence of experimental conditions on hardness and elastic modulus are also reported and discussed.
