【摘要】：通过在无规共聚聚丙烯(PP-R)中添加聚二苯氧基磷腈(PDPP),进行熔融共混改性制备PP-R/PDPP复合材料,分析PDPP对PP-R复合材料力学性能和热学性能的影响。结果表明,PDPP的加入使得PP-R的晶型由原来单一的α晶型转变为α与β混合晶型;复合材料的拉伸强度、断裂伸长率和弯曲强度均随PDPP含量的增加而提高;PP-R/PDPP共混物具有比PP-R更高的热稳定性。
[Abstract]:PP-R/PDPP composites were prepared by melt blending of polydiphenoxy phosphorylonitrile (PDPPN) with PP-R, and the effects of PDPP on the mechanical and thermal properties of PP-R composites were analyzed. The results show that the crystal form of PP-R is changed from a single crystal form to a mixed crystal form of 伪 and 尾, and the tensile strength of the composite is obtained. The elongation at break and bending strength of PP-R / PDPP blends increased with the increase of PDPP content, and the thermal stability of PP-R / PDPP blends was higher than that of PP-R.
