发明名称 Anionic copolymers prepared in an inverse emulsion matrix and their use in preparing cellulosic fiber compositions
摘要 <p>A papermaking method and a composition which utilize, as a drainage aid, a water-soluble anionic copolymer prepared via a water-in-oil polymerization technique that, absent a crosslinking agent, is characterized by a Huggins' constant (k') determined in 0.01M NaCl greater than 0.75 and a storage modulus (G') for a 1.5 wt.% actives polymer solution at 4.6 Hz greater than 175 Pa.</p>
