Aliphatic-aromatic hyperbranched polyesters of reasonable degrees of branching (DB's) but of relatively low molar masses were prepared from 3,5-bis(bromo-methyl) benzoic acid (2a). 2a was synthesized by radical bromination of 3,5-dimethylbenzoic acid

Potassium 3-bromomethyl-5-methylbenzoate 2K, preformed or obtained from 3-bromomethyl-5-methylbenzoic acid 2 by exchange reaction with potassium undecanoate 5K, was polymerized in bulk or in 1-methyl-2-pyrrolidone (NMP), in the presence or not of a t

Nucleophiles such as alcohols and diols, water and amines initiate the bulk polymerization of cyclic trimethylene carbonate (TMC, 1, 3-dioxan-2-one) at 100-120°C in the absence of added catalysts. TMC is ring-opened by attack of the carbonyl carbon
