UNMIXING KINETICS AND ITS MORPHOLOGY OF POLY ( ETHYLENE OXIDE) WITH POLYETHERSULPHONES BLENDS
摘要:
Unmixing kinetics in a binary polymer mixture of polyethersulphones with poly (ethylene oxide) by spinodal decomposition has been investigated with time-resolved light scattering and microscope methods. The results showed that time evolution of scattered light intensity is of an exponential growth The maximum growth rate R(qm) of phase separation has been obtained. The experimental data did not satisfy the condition that the plot of R(q)/q2 vs q2 should be linear For unmixing system annealing at 30℃ for three hours its morphology manifested dish structure The expenmental data of the Bragg spacing Dm can be correlated with a straight line which expresses the power-law relation,Dm=bta.
