【Abstract】 Allyl ether phenolic resin was synthesised ,then it was copolymerized with bismaleimide.Its properties were characterized by FTIR and DTA. The study result showed that phenolic resin modified by bismaleimide had excellent heat resistance ,and the heat decomposition temperature came up to 469℃. In addition ,the resin had suitable softening point,which could be used in resin abrasive products with heat press.更多还原
