CATIONIC OR AMPHOTERIC COPOLYMERS PREPARED IN AN INVERSE EMULSION MATRIX AND THEIR USE IN PREPARING CELLULOSIC FIBER COMPOSITIONS

摘要

A papermaking method and a composition which utilize, as a drainage aid, a water-soluble cationic or amphoteric copolymer prepared via a water-in-oil polymerization technique that, absent a cross-linking agent, is characterized by a Huggins' constant (k') determined in 0.01 M NaCl greater than 0.3 and a storage modulus (G') at 6.3 Hz greater than 50 Pa.
