摘要： Disclosed are compositions and methods useful in applications relating to papermaking. The compositions and methods of the present invention comprise aldehyde-functionalized polymers designed to impart high paper strength and enhance water removal during the papermaking process. The aldehyde-functionalized polymers are of relatively low molecular weight, and comprise amino and/or amide groups mono-reacted and di-reacted at a ratio of at least about 1.5 to 1. The low molecular weight polymers of the present invention have the same strength and dewatering performance as corresponding high molecular weight polymers.
