Abstract

The activators regenerated by electron transfer–atom transfer radical polymerization (ARGET–ATRP) technique was utilized in the emulsion copolymerization of 2-ethylhexyl acrylate (2-EHA), ethyl acrylate (EA) and methyl methacrylate (MMA) as the copolymer raw material, and ethyl 2-bromoisobutyrate (EBIB) was used as the initiator in a pentamethyldivinyltriamine (PMDETA)/copper bromide-catalyzed system for emulsion copolymerization. The effects of the reaction temperature, reducing agent ascorbic acid (AA) dosage and ligand concentration on the copolymerization kinetics were investigated. The synthesized polymers were characterized by proton nuclear magnetic resonance (1H NMR) spectroscopy and infrared (IR) spectroscopy. The results showed that the copolymerization monomers added to the reaction were successfully initiated by the initiator and polymerized into terpolymers, the conversion rate of the monomers gradually increased with increasing amounts of ligand and reductant, and the conversion rate of the monomers involved in the copolymerization reaction and the apparent reaction constants gradually increased with increasing reaction temperature. The apparent activation energy of the copolymerization reaction, Ea, was calculated to be 80.43 kJ·mol-1.


Keywords: activators regenerated by electron transfer–atom transfer radical polymerization, kinetics, emulsion copolymerization, apparent activation energy, apparent polymerization rate constant
