By using AIBA·2HCl-NaHSO3 initiation system,a series of high intrinsic viscosity copolymers of dimethyl diallyl ammonium chloride(DMDAAC) and acrylamide(AM) were prepared in aqueous medium under different conditions.The effects of various factors such as initiator concentration
pH of solution
composite initiator and the way of feeding AM etc.on the copolymerization of dimethyl diallyl ammonium chloride and acrylamide were studied. The results indicated that copolymerization could be initiated at a low temperature.At 30℃
nAM∶nDMDAAC=4∶1
ω(monomer)=30%
c(AIBA·2HCl)=1.0×10-4 mol·L-1,when the monomer solution was polymerized at pH=7.0,the intrinsic viscosity of PDMDAAC-AM was 11.56 dl·g-1;when the monomer solution was polymerized at pH=10.0,the intrinsic viscosity of copolymer was up to 13.60 dl·g-1.If continuous feeding of AM was used
the cationicity and intrinsic viscosity of copolymer could attain 38.8% and 11.61 dl·g-1.Furthermore
the monomer reactivity ratios and apparent activation energy of the polymerization system were determined.
