Abstract

A new catalytic system composed of anhydrous rare earth chloride and 50% fuming sulfuric acid has been developed for the homopolymerization of tetrahydrofuan (THF) and the copolymerization of THF with chloromethyl thiirane (CMT).The polymerization characteristics of THF were examined.White solid PTHF with high conversion of 65% and high viscosity molecular weight of 10

000～15

000 can be obtained at 0 to -15℃ in about 5 hour.The molecular chain of PTHF has average two hydroxyl groups.The effects of copolymerization parameters such as temperature

duration and comonomer ratio on the copolymerization of THF with CMT were studied.
