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.
