Abstract

The invention relates to an allyl-terminated arylsulphone ether polymer and a preparation method thereof. The molecular structure general formula of the allyl-terminated arylsulphone ether polymer is shown in the specification. The epoxy resin composition has excellent comprehensive performance, not only has good compatibility with various epoxy resins such as bisphenol A type epoxy resin, glycidyl amine type epoxy resin, phenolic aldehyde type epoxy resin and the like, but also has good toughening property, improved high temperature resistance, hydrophobicity, dielectric property and the like for the epoxy resins, and has good chemical reaction activity.

Description

technical field [0001] The invention belongs to the field of polymers, in particular to an allyl-terminated aryl sulfone ether polymer and a preparation method thereof. Background technique [0002] Polysulfone and polyethersulfone are amorphous thermoplastic new special engineering plastics with sulfone groups, ether bonds and aromatic nuclei. The sulfur atom in the sulfone group is in the highest oxidation state, so the oxidation resistance, mechanical properties and thermal stability are relatively high. Well, the presence of ether linkages again provides some toughness. In addition, polysulfone and polyethersulfone are non-toxic, chemically resistant, and inherently flame retardant. Therefore, polysulfone and polyethersulfone are widely used in electronic appliances, automobile machinery, aerospace and other fields. [0003] BASF's UltrasonS and UltrasonE products based on polysulfone / polyethersulfone have good dimensional stability and water and oil resistance at high...
