Continuous prepn. of homogeneous polymer soln. - by kneading polymer suspension in solvent at high shear rate, for filaments and tapes

摘要

In continuous prepn. of homogeneous solns. of high mol. polymers, a finely divided polymer is suspended in a solvent, and the suspension is mixed and kneaded at a high mechanical shear rate and at increased temp. for 0.5-30 mins., in a zone with high feed rate.
