Paper quality improver |
| abstract |
An additive for internal addition that significantly improves the paper quality of a pulp sheet is provided. A synthetic cationic polymer having an aqueous solution (7% by mass) viscosity of 20 mPa · s (50 ° C.) or more and a nitrogen content of 1.0% by mass or less, and a Tg having a structural unit derived from a vinyl monomer. An internal paper quality improver comprising a polymer emulsion containing polymer particles having a temperature of 90 ° C. or lower. [Selection diagram] None |
