GRAFT-COPOLYMERS HAVING HYDROPHOBIC BACKBONE AND HYDROPHILIC BRANCHES .8. EFFECT OF TEMPERATURE ON THE DISPERSION COPOLYMERIZATION OF POLY(ETHYLENE GLYCOL) MACROMONOMER WITH STYRENE

Copolymerization of poly(ethylene glycol) macromonomers with terminal methacryloyl groups with styrene was carried out in the presence of 2,2'-azobis(N,N'-dimethyleneisobutyramidine) in ethanol/water mixture (4: 1, v/v) at various temperatures. The overall activation energy for the dispersion copolymerization was obtained as 48 kJ/mol.
