КАТИОНОАКТИВНЫЕ ИЛИ АМФОТЕРНЫЕ СОПОЛИМЕРЫ, ПОЛУЧЕННЫЕ В МАТРИЦЕ ОБРАЩЕННОЙ ЭМУЛЬСИИ, И ИХ ПРИМЕНЕНИЕ ПРИ ПРИГОТОВЛЕНИИ КОМПОЗИЦИЙ ЦЕЛЛЮЛОЗНОГО ВОЛОКНА

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 0.01M NaCl greater than 0.3 and a storage modulus (G') at 6.3 Hz greater than 50 Pa.
