Solvent blends based on dipropylene glycol dimethyl ether (DPGDME) and non-HAP hydrocarbons were evaluated as replacements for the preparation of alkyd and polyester resins by the solvent reflux process. Screening criteria included water partitioning properties, autoignition temperature, distillation profile, and water removal efficiency. A series of resins was also prepared by an identical procedure in order to compare the performance of the DPGDME solvent blends with that of the xyl
