采用TiO 2/聚氧化乙烯光催化降解聚丙烯（PP），并与亚油酸甲酯（ML）进行接枝聚合反应。凝胶渗透色谱和核磁共振测试表明，它是由PP主链和ML低聚物侧链组成的低聚物。采用PP/微纤维状纤维素（MFC）复合材料研究了PP低聚物的增容性能。以马来酸酐化聚丙烯（MAPP）为对照，研究了PP/MFC复合材料的形态结构和拉伸性能。PP低聚物的负载带来了良好的分散性的MFC在PP基体中。加入0.75%PP低聚物后，复合材料的杨氏模量比未加低聚物时提高了300%。其分散性和模量增长率均优于MAPP的上级负载量。与PP基体相容性好是增容剂性能优异的原因。
Polypropylene (PP) oligomer was prepared by combination of photodegradation with a TiO2/polyethylene oxide and methyl linoleate (ML) graft-polymerization. The gel permeation chromatography and nuclear magnetic resonance measurements showed that it was an oligomer compound composed of PP main chain and ML oligomer side one. A compatibilizer performance of the PP oligomer was studied using a PP/microfibrous cellulose (MFC) composite. The effects of the loading on the morphology and tensile properties of PP/MFC composite were investigated as compared with those of the maleated PP (MAPP) loading. The PP oligomer loading brought about good dispersity of the MFC in the PP matrix. Young’s modulus value of 0.75 % PP oligomer loading composite was increased to 300 % as compared with that without the loading. The dispersity and modulus increment rate were superior to the MAPP loading. The excellent compatibilizer performance was due to good miscibility with the PP matrix.
