高性能工程塑料的流变和加工性能：I.酞侧基聚芳醚酮的毛细管挤出行为

摘要

cqvip:The capillary flow property and processability of the title plastics (PEK-C) havebeen investigated using capillary rheometer. The dependence of the viscosity on the wallshear rate and temperature were obtained. The swelling of the extrudate was measured andthe fracture phenomena of the extrudate were discussed.
