This paper studies the application of composite catalytic system of ether-derivative/AlCl 3 in synthesis of pipevylene resin, evaluates and chooses a homogeneous composite catalytic system and examines the influences of it on the yield, softening point, compatibility, molecular weight and its distribution of the resin.The results indicate that this composite catalytic system can raise the softening point, improve the compatibility, increase the molecular weight and decrease its distribution, and the yield of reaction can also maintain a relatively high level.
