Diallylamine copolymer, process for producing the same, and treating agent for hard surface

摘要

PROBLEM TO BE SOLVED: To provide a new diallylamine-based copolymer useful as a component of a treating agent for a rigid surface; to provide a method for producing the copolymer; and to provide the treating agent for the rigid surface containing the copolymer.;SOLUTION: The diallylamine-based copolymer has a constituent unit derived from diallylamines, a constituent unit derived from an ethylenically unsaturated sulfonic acid compound and/or an ethylenically unsaturated carboxylic acid compound, and a constituent unit derived from sulfur dioxide. The method for producing the diallylamine-based copolymer involves copolymerizing monomers constituting each of the above constituent units in a polar solvent in the presence of a radical initiator. The treating agent for the rigid surface contains the diallylamine-based copolymer.;COPYRIGHT: (C)2007,JPO&INPIT
