摘　　要：本文在研究废旧PP的加工热稳定行为的基础上，将UPR预固化处理后与废旧PP熔体共混，制备PP／UPR共混材料。研究结果表明，UPR在基体中以颗粒分散的形式存在，其加入可以大幅度提高体系的力学性能；此外，共混体系的力学性能改善应部分归于UPR诱导PP结晶。The thermo--stability of recycled PP were investigated first in this paper, after which PP/UPR blends were prepared by melt mixing of recycled PP and procuring UPtL The results showed that UPR dispersed in the PP matrix in the form of particles, and the mechanic properties of the blends improved greatly with the addition of UPtL The analysis showed that UPR particles act as the nucleating points of PP, increasing the crystallinity of PP and improving the mechanical properties.
