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。By adding poly diphenoxy phosphazene （PDPP） into polypropylene random copolymer （PP-R）,PP-R/ PDPP composite material were prepared by melt blending of PDPP and PP-R. The mechanical and thermal performances of system were studied. The results showed that the crystal form of PP-R induced a crystalline converted to a mixed form of and β crystalline while the PDPP was added. The tensile strength,elongation at break and bending strength of material increased with the increase of PDPP content. PP-R/PDPP material was much more stable than PP-R.
