Title:

(METH)ACRYLAMIDE POLYMER, PROCESS FOR PRODUCTION THEREOF, PAPER MAKING CHEMICALS, PAPERS CONTAINING THE SAME

Document Type and Number:

WIPO Patent Application WO/2003/070796

Kind Code:

A1

Abstract:

A novel (meth)acrylamide polymer capable of forming paper making chemicals which exhibit excellent paper-strengthening, drainage-improving, yield-improving, interlaminar strength enhancing, surface strength enhancing, sizing-improving effects in acid, neutral, or alkaline paper-making systems; a process for production thereof; and papers made by using the polymer and being excellent in burst strength, internal bond strength and other characteristics. The (meth)acrylamide polymer is characterized by being obtained by polymerizing (a) a monomer represented by the general formula (1) with (b) (meth)acrylamide and (c) an ionic monomer exclusive of the monomers represented by the general formula (1).
