| Title of Invention | A PROCESS OF MAKING PAPER |
|---|---|
| Abstract | Paper is made by a dual soluble polymer process in which a cellulosic suspension which usually contains alum or cationic coagulant is first flocculated with a high IV cationic synthetic polymer or cationic starch and, after shearing, the suspension is reflocculated by the addition of a branched anionic water soluble polymer having IV above 3dl/g and tan delta at 0.005Hz of at least 0.5. The process gives an improved combination of formation, retention and drainage. |
