【摘要】 用氢氧化钾做引发剂合成了不同分子量的聚缩水甘油苄基醚预聚体(PBzGE),对其碳谱进行了详细的归属,再用浓硫酸进行磺化,得到不同磺化度的磺酸聚醚(SPBzGE)。通过VPO,NMR,FT-IR测试了聚醚预聚体的分子量,并且对预聚体的结构进行了详细的归属。制得了分子量在1000～3000的预聚体,SPBzGE的磺化度大于110%。更多还原

【Abstract】 A serious of poly benzyl glycidyl ether with different molecular weight were synthesised using the Potassium hydroxide as initiator.The detail signals between 80 and 60 ppm of benzyl glycidyl ether were assigned.Sodium poly benzyl glycidyl ether sulfonate were synthesis via the sulonation of poly benzyl glycidyl ether with sulfuric acid.The polymer and sulfonate were characterized with VPO,NMR,FT-IR.The result shows that the number average molecular weight of PBzGE were in the range of 1000～3000 and its sulfonation degree can be more than 110%.更多还原
