摘　　要：在聚丙烯熔融接枝马来酸酐(MAH)中引入有机蒙脱土(OMMT),讨论了OMMT/DCP(1∶1)、MAH的加入量对PP接枝率以及分子量的影响。结果表明PP接枝MAH的接枝率大大提高,减小了PP链的裂解。In this research, we introduce into the graft process a kind of laminated silicate-organic montmorillonite (OMMT) which can absorb added peroxide DCP in its' gallery; we discuss how the added OMMT/DCP(1∶1) and MA influence PP's MA-grated rate and average molecular weight. The experimental results show that melting graft PP product achieve higher maleic anhydride (MA) grfted rate and encounter less β-scission and decomposition.
