POLYMER SUITABLE FOR PAPER MAKING ADDITIVES AND PROCESS OF MANUFACTURING THEM

摘要

PURPOSE: A polymer and a cationic polymer obtainable by Hofmann degradation of polymer are useful paper making additives such as paper strength agents, drainage aids and surface coatings. CONSTITUTION: A polymer(A) is prepared by polymerizing one or more vinyl monomers(c) in the presence of a polymer(A) prepared by polymerizing one or more vinyl monomers(a) selected from the group consisting of vinyl monomers represented by the general formula(1): wherein R1 represents a hydrogen atom or a lower alkyl with 1 to 3 carbon atoms and n is an integer of 1 to 8 and their salts with one or more vinyl monomers(b) which are copolymerizable with the vinyl monomer components(a).
