Description

키토산과 아크릴산의 그라프트 공중합체 제조 방법Method for preparing graft copolymer of chitosan and acrylic acid

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 키토산(A)과 본 발명에 의한 공중합체(B)의 IR스펙트럼이며,1 is an IR spectrum of chitosan (A) and the copolymer (B) according to the present invention,

제2도는 본 발명에 의한 공중합체를 응집제로 사용한 경우 응집제 첨가량에 따른 응집효과를 아크릴산의 단일 중합체와 비교한 것이며,2 is a comparison of the coagulation effect according to the amount of coagulant added to the homopolymer of acrylic acid when the copolymer according to the present invention is used as a coagulant.

제3도는 본 발명에 의한 공중합체의 pH에 따른 응집효과를 나타낸 것이다.Figure 3 shows the coagulation effect according to the pH of the copolymer according to the present invention.
