【Abstract】 In PP/PS blend, PP is matrix and PS is modified component. PP/PS blend is thermodynamically incompatible system, but the blend can gain good technological consistency by choosing proper additive PS. The research results of spinning and drawing show that the spinnability of PP/PS blends is good(dpf<1) and the physicomechanical properties of the fiber have been improved significantly.更多还原
