| Abstract: | The precipitation copolymerization of acrylamide and hexadecyl acrylate has been carried out in DMF at 80℃ using benzoyl peroxide as initiator.The study emphasized on the relationships between the composition of copolymers and the thickening power of copolymers on emulsion.The effects of the amount of initiator,mole ratio of monomers, solvents and reaction temperature on the polymerization reaction were investigated.The copolymers were characterized by DMTA and Kjeldahl method for nitrogen determination.The experimental results show that the molecular weight of P(AM-HT) copolymers is high enough for hydrophobically associative thickening agent. |
