摘要： Water-in-oil emulsions of cationic water-soluble copolymers which are prepared by incorporating only a portion of the cationic monomer in the aqueous phase prior to forming the water-in-oil emulsion in which polymerization will occur, forming the emulsion, adding the balance of the cationic monomer such that essentially no polymerization occurs immediately after the addition, and polymerizing the monomers. Copolymers prepared by this process show improved performance over conventionally prepared cationic copolymers.

摘要： An improved cationic water-soluble polymer is prepared from acrylamide, a cationic monomer such as dimethylaminoethyl methacrylate dimethylsulfate quaternary, and a waste stream which is produced as a result of the transesterification reaction between dialkylamino alcohols and acrylates which is used to prepare the cationic monomer. The polymers are especially useful in dewatering applications.
