위의 식에서, a, b 및 c는 0 이상의 정수로서 반응물 각각의 몰수에 의존한다.Wherein a, b and c are integers greater than or equal to 0 depending on the number of moles of each of the reactants.

본 발명은 낮은 온도에서 반응 원료를 중합시켜 고분자량의 중합체를 얻으며, 양이온성 단량체에 술폰기를 도입시키고 제품 자체도 미세하게 분산되어 있으므로 용해성을 극대화하였으며, 카르복시메틸셀룰로즈 등을 사용하여 고농도의 중합체를 안정하게 분산시켜 장기간에 걸쳐 보관안정성을 유지되는 등의 우수한 장점을 보유한다.The present invention polymerizes the reaction raw material at a low temperature to obtain a high molecular weight polymer, introducing sulfone groups into the cationic monomer, and the product itself is finely dispersed, thereby maximizing solubility, using carboxymethyl cellulose, etc. It has excellent advantages such as stable dispersion and maintenance of storage stability over a long period of time.
