摘要
Abstract
A novel cardo poly(aryl ether ketone) bearing pendant epoxy group with controlled content(PEKHE) was prepared,by nucleophilic polycondensation from 3,3-bis (4-hydroxyphenyl) benzo pyrrolone (HPP)with 4,4'-diflorobenzophenone,followed by a substitution reaction with epichlorohydrin(ECH).The content of epoxy side group could be controlled via altering the amount of reactant monomer.Structure and properties were characterized and tested by FHR,1H NMR,TGA,etc.Properties of the PEK-HE coating were investigated after self-curing.Thermal stability of the coating layer was obviously improved compared to that before curing,and 5％ mass loss temperature was all over 450 ℃.The layers had excellent thermal and mechanical properties:heat-resistant temperatures were (350 ± 20) ℃,the impact strength were all above 100 kg·cm.Thus the PEK-HE was expected for the application of high performance self-curing coating.关键词
