불소계 아크릴레이트 공중합체 중합, 평균분자량 및 내열성에 미치는 중합개시제 영향성

초록

The effects of radical initiator on the emulsion polymerization using a mainmonomer, such as n-butyl acrylate or cyclohexyl acrylate, and a co-monomer, perfluoro acrylate, were examined. As a radical initiator, 3 kinds of initiator, KPS, AIBN, TBPB were used in the polymerization, then the average molecular weight and PDI value, and the thermal stability of the copolymers synthesized were evaluated by a Gel Permeation Chromatography (GPC) and a Thermogravimetric Analyzer (TGA), respectively. Two types of radical initiator, AIBN and TBPB, exerted higher molecular weight than that of KPS. The PDI values of the copolymers were analyzed by 1.44-5.26 depending on the monomer structure and the ratio of two monomers, and it was also observed that the PDI values showed a proportional relationship on the thermal stability.
