Fund Project:

In the presence of catalyst BF₃·OEt₂, using ethylene glycol as initiator and CH₂Cl₂ as solvent hydroxylterminated poly(cyclohexene oxide)(PCHO) was synthesized by cationic ring opening polymerization of monomer cyclohexene oxide(CHO). The effect of catalyst amount, polymerization temperature and polymerization time on polymerization results were discussed. The best technical condition was:polymerization temperature 0℃, n(BF₃·OEt₂)/n(CHO)=0.02, n(EG)/n(CHO)=0.01, polymerization time 5 h. The average molecular weight of PCHO obtained was about 1 200, and the conversion of polymer could be up to 92%. The structure of the product was identified by IR and ¹H NMR.
