Abstract

To accelerate the biodegradability of poly(vinyl acetate)‐based emulsions, emulsion copolymerizations of vinyl sugars, including triacetylated N‐acetyl‐D‐glucosamine (GlcNAc)‐substituted 2‐hydroxyethyl methacrylate (GlcNAc(Ac)~3~‐substituted HEMA), glucose‐substituted HEMA (GEMA) and 6‐O‐vinyladipoyl‐D‐glucose (6‐O‐VAG) with vinyl acetate (VAc), were carried out using poly(vinyl alcohol) as an emulsifying agent in the presence of poly[(butylene succinate)‐co‐(butylene adipate)] [poly(BS‐co‐BA)]. Copolymerization with GEMA produced a stable emulsion and that with 6‐O‐VAG also produced a homogeneous emulsion. Their biodegradation tests indicated that PVAc main chain scission was accelerated by copolymerization with vinyl sugars.
