摘要：This invention is directed to a method of improving retention and drainageperformance in a papermaking process comprising adding to the furnish an effectiveamount of a low molecular weight water-soluble cationic dispersion polymer preparedby polymerizing one or more cationic monomers and one or more nonionic monomersand one or more chain transfer agents under free radical forming conditions in anaqueous solution of an anionic salt in the presence of a stabilizer polymer, wherein thecationic dispersion has a cationic charge of from about 10 mole percent to about 80 molepercent and an RSV of from about 0.2 dl/g to about 6 dl/g.
