摘　　要：以聚丙烯（PP）树脂与降解材料聚乳酸（PLA）组成的共混体系为主要研究对象，探索PP／PLA共混体系的流动性能。列其240℃下τ-y流变曲线、240℃下熔体表观黏度与组成和剪切速率的关系及熔体表观黏度与加工温度的关系作了概述。Take the （PP） resin and the degeneration material gather lactic acid as the polypropylene/ （PLA） to compose altogether mixing system and as the main research object, explores PP/PLA altogether to mix the system to the flow properties. To its 240℃ under tau - gamma flow curve, 240 ℃ under melt the body surface view viscosity with to compose and the shear rate relations and the melt body surface view viscosity and the processing temperature relations have made the outline.

关 键 词：聚丙烯 聚乳酸 流动性能 表观黏度
