Method of increasing paper strength |
| abstract |
The invention provides methods and compositions for increasing the strength of a paper sheet. The method involves adding to the paper sheet an amine containing polymer. The amine containing polymer interacts with materials such as GPAM or starch to make the paper stronger in terms including tensile strength, surface strength and bulk strength. |
