초록
올리고머에 유리전이온도가 낮은 기능성 단량체를 주단량체로 혼합하고, 화학구조가 다른 단량체들을 부단량체로 도입한 프리폴리머의 박리 강도 및 점탄성 거동을 측정하였다. 올리고머 분자량과 기능성 단량체들간 화학구조가 접착제의 물성에 미치는 영향을 비교하였다. 올리고머, 기능성 주단량체 및 공단량체로 구성된 프리폴리머의 자유 라디칼 공중합 시 라디칼 구조에 따른 반응성 비 차에 의해, 형성되는 고분자 사슬들이 변하고 접착제의 물성도 달라진다.
The peel strength and the viscoelastic behavior of prepolymer by mixing functional monomers having low glass transition temperature with oligomer and including monomers with different chemical structure were measured. The effect of oligomer molecular weight and chemical structure between functional monomers on adhesive properties were compared. In the free radical copolymerization of prepolymer composed of oligomer, functional main monomers, and additive monomers, the polymer chains formed are altered and the physical properties of the adhesive are modified by the difference of reactivity ratio according to the radical structure.
