METHOD OF DISPERSING EVENLY PARTICLE INTO POLYMER

摘要

PURPOSE:To provide a method of dispersing inactive particles into a molten polymer in an individual state. CONSTITUTION:Molten polymer and 0.005-4wt.% inactive particles of 0.005-5mum in size are premixed in an extruder. The premixture is passed through at least tow kinds of porous bodies containing porous sinter of nonwoven metallic fiber and porous sinter of metal particles so that the particles are dispersed evenly in polymer.
