The polymerization of acrylic acid (AA) with dissolved carbon dioxide and tetrahydrofuran (THF) in the monomer is studied. Viscosity measurement, differential scanning calorimetn (DSC). and scanning electron microscopy (SEM) indicate that the concentration of tetrahvdrofuran has pronounced effect on the molecular weight (Mη). glass transition temperature (Tg), and the morphology ofthe product.
