## Abstract A series of novel biodegradable random copolymers of 5βbenzyloxyβ1,3βdioxanβ2βone (5βbenzyloxyβtrimethylene carbonate, BTMC) and glycolide were synthesized by ringβopening polymerization. The copolymers were characterized by nuclear magnetic resonance (NMR) spectroscopy and gel permeati
A new four-armed poly(1,3-dioxepane) tetraol was prepared by cationic ring-opening polymerization of 1,3-dioxepane (DOP) in the presence of 6,6-bis(5-hydroxyl-2-oxapentyl)-4,8-dioxaundecanediol-1,11 (THA) with triflic acid(I) as initiator. The structure of the poly(DOP) tetraol obtained was characte
