Stability Study of Chitosan-g-AM Inverse Emulsion

Abstract:

Graft copolymerization of chitosan and vinyl monomer (such as acryamide and acrylic acid) and application study of the copolymer used as papermaking additive were paid more and more attention in papermaking chemical industry. Chitosan and acrylamide(AM) monomer were graft copolymerizing in inverse emulsion. Several factors such as oil-water proportion, mass ratio of chitosan and AM, emulsifier types and ratio, and initiator concentration that affect the stability of inverse emulsion were elementarily studied. Stable latex can be gained when reaction condition was that the volume ratio of oil phase and water phase was 1:1, the weight ratio of chitosan and AM was 1:8, the initiator concentration was 0.8mmol/L, the dosage of emulsification agent was 8% of the oil phase weight and the weight ratio of 1227 and OP-10 was 1:1.
