Two types of polymer blends: poly(glycidyl methacrylate)/poly(propylene glycol) (PPG) and poly(triethylene glycol dimethacrylate)/PPG were obtained by means of photopolymerization of PPGs solutions in corresponding monomers. During the polymerization phase separation occurred. The range of conversions where cloud points occur were determined as a function of the molecular weight (MW) of PPG used. It was found that the polymerization rate was controlled by the initial viscosity of the system and the quality of PPG used as the solvent.
