ABSTRACT:
A method of preparing paper or paper board product from an aqueous pulp suspension comprising adding to the suspension an effective amount of a drainage retention aid composition of a) microparticles and b) at least one water soluble cationic polymer selected from a water soluble cationic copolymer composed of the polymerization reaction of an N-vinylamide with at least one cationic quaternary amine monomer.
The copolymers of this invention are useful as useful as drainage/retention aids in pulp and papermaking operations.
