Because of the growing interest in bis-MPA dendrimers and hyperbranched polymers, a linear, polyester equivalent is of great importance in understanding how this commercially viable family of branched polymers behaves when compared to their linear analogs. Herein, we describe the first synthesis and characterization of a novel, linear, chain-growth bis-MPA homopolyester that can be used for such an investigation. Linear benzoyl bis-MPA or poly(3-(benzoyloxy)-2-(bromomethyl)-2-methylpropanoic acid) (PBBM) was synthesized efficiently using a small molecule brominated bis-MPA derivative followed by a chain-addition polymerization using potassium carbonate (K2CO3). This polymerization can take place in a range of solvents with low dispersity values (<1.2). The polymerization mechanism and the postfunctionalization of PBBM are discussed. A preliminary solution size comparison using gel permeation chromatography (GPC) was also conducted with respect to benzylidene-protected bis-MPA dendrimers.
