丙烯腈溶液接枝聚丙烯的研究

Study on grafting reaction of acrylonitrile onto solution polypropylene

以丙烯腈(AN)为接枝单体溶液接枝聚丙烯(PP),研究丙烯腈(AN)的量,偶氮二异丁腈(AIBN)和过氧化二异丙苯(DCPO)的组成及量,反应条件对接枝率的影响。试验结果表明,在合适的引发剂用量和反应条件下,丙稀腈能较好的接枝到聚丙稀上。

The grafting reaction of acrylonitrile (AN) onto solution polypropylene(PP) has been discussed,In the reaction between AN and dicumyl peroxide(DCPO) or azobisisobutyronitrile(AIBN) as initiator, Influence of the composition of the reaction mixture and of some reaction comdition on the degree of grafting of products has been investigated .It was proved That the presence of DCPO and AIBN have great effect on the degradation of PP,The grafting reaction of AN is well in moderate reaction comdition .
