β-chloroethyl glycidyl ether and its polymer poly (β-chloroethyl glycidyl ether ) have been synthesised. The results show that AlEt3-0.5H2O 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.
