pitch control agent and pitch control method |
| abstract |
a pitch control agent including an amphoteric polymer based on (meth) acrylamide is described. the (meth) acrylamide-based amphoteric polymer contains 50 mol% or more of (meth) acrylamide, 0.5 to 20 mol% of a diallyldialkylammonium salt; and 0.1 to 14 mol% of an anionic monomer, as copolymerizable monomer components. this pitch control agent is less likely to be affected by a change in an adjacent environment, and therefore can exhibit excellent pitch controllability under various environments in the papermaking process. |
