Study on Synthesis of Cationic Polymethyl Acrylate Emulsion

Abstract:

Emulsion copolymerization of methyl acrylate, styrene, acrylamide, acrylonitrile and homemade cationic monomer was studied. A series of clean cationic polymethyl acrylate emulsion were synthesized using no soap emulsion polymerization. Influence of polymerization conditions such as cationic monomer ratio, electrolyte addition amount, the dosage of initiator on synthetic latex performance and the strengthening effect to paper pulp was studied. It was showed by experimental results that sample No.3 which particle size and zeta potential was 0.142 μm and +29.2 mv respectively was the optimal sample latex. When the dosage of latex No.3 was 1.0% to absolute dry pulp, tensile index and ring crush index of paper was increased by 14.6% and 17.8% respectively.
