| 摘 要： | The living chains were obtained in the bulk copolymerization of tetrahydrofuran (THF) withpropylene oxide (PO) (10--20 wt.%) initiated by adipoyl chloride (AC)AgC10_4 ([ACl0,=0.02-0.09 mo1.1~(-1)) catalyst at-10--0℃without chain termination and transfer reactions. The estimationof reactivity ratios gave values of 0.8±0.2 and 0.08±0.03 for THF and PO, respectively. The func-tionality of living chains with 10% PO in the feed is close to 2. Four different telechelic THF-PO co-polymers with amine or hydroxyl end-groups [P(THF-co-PO)R, where R=-NHBu,-NHPh,-NEt_2 or--OH were synthesized.
