| Abstract: | The synthesis of a liquid styrene-butadiene-styrene block copolymer(SBS) was described.The favorable conditions for epoxidation of SBS were as follows:reactive temperature 60 ℃,receptive time 3 h,SBS∶benzene=1∶1(weight ratio),SBS∶hydrogenproxide=2∶1～1.3 (weight ratio),acetic acid∶hydrogenproxide=1∶1(mole ratio).The epoxy group content of product was 14%～16%.The hydroxyl group content of product was 2.9%～3.2%. The epoxide of SBS was used to make rubber-like product to make epoxy ester lacquer,to toughen epoxy resin and so on. |
