Retention and drainage in the manufacture of paper |
| abstract |
A method of improving retention and drainage in a papermaking process is disclosed. The addition of an associative polymer, a poly(vinylamine) and optionally a siliceous material to the papermaking slurry to improve retention and drainage is disclosed. Additionally a method to improve retention and drainage comprising addition of an organic microparticle, a poly(vinylamine) and optionally a siliceous material to the papermaking slurry is disclosed. A composition comprising an associative polymer, and a poly(vinylamine) and optionally further comprising cellulose fiber is disclosed. |
