DICATIONICALLY LIVING CHAINS: COPOLYMERIZATION OF TETRAHYDROFURAN WITH PROPYLENE OXIDE AND SYNTHESIS OF THE TELECHELIC OLIGOMERS*
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)AgC104 ([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-grpups [P(THF-co-PO)R,where R=-NHBu、-NHPh,-NET2 or -OH were synthesized.
