摘　　要：本文合成了β－氯乙基缩水甘油醚及其聚合物。结果表明，ＡｌＥｔ３－０．５Ｈ２Ｏ体系是β－氯乙基缩水甘油醚的一种有效的聚合引发剂。研究了聚的酯化反应动力学，并通过＾１ＨＮＭＲ和ＩＲ光谱确立了酯化度的计算关系式。最后，通过光交联的动力学研究发现，酯化聚合物中的肉桂酰基含量为８５％时，材料的感光灵敏度最高。β-chloroethyl glycidyl ether and its polymer poly (β-chloroethyl glycidyl ether) have been synthesised. The results show that AlEt3-0.5 H2O system is a effective polymerization initiator for β-chloroethyl glycidyl ether. Moreover, the kinetic of esterification of the poly (β-chloroethyl glycidyl ether) was studied, and the calculation formula of esterification degree by 1H NMR and IR spectroscopy was established. Finaly, with the aid of kinetic investigation of photocrosslinking the esterificated polymer with a 85% of cinnamate which a highest photosensibility of the material was found.
