Abstract

A new tetrafunctional monomer, [(oxybis(methylene)] bis(2-ethylpropane-2,1,3-triyl)tetrakis(oxy)tetrakis(3-oxopropane-3,1-diyl) tetraacrylate (DTMP-CEA), was synthesized through a condensation reaction between di(trimethylolpropane), containing hydroxyl groups, and 2-carboxyethylacrylate. The chemical structure of the synthesized monomer was confirmed by NMR and FT-IR analyses. DTMP-CEA was compared with the commercialized EB-40 monomer by evaluating properties such as molecular weight distribution, viscosity, adhesion, and performance in UV ink applications. GPC analysis showed that EB-40 consists of a mixture of molecules with various molecular weights, while DTMP-CEA is a single molecule. Bond shear strength measurements revealed values of 725.3 N for DTMP-CEA and 158.3 N for EB-40, indicating that the newly developed monomer has approximately 4.6 times improved bond shear strength. Furthermore, when applied to cyan UV ink, DTMP-CEA exhibited a cure speed that was over 10% faster than EB-40.

수산기를 함유한 di(trimethylolpropane)와 2-carboxyethylacrylate를 축합반응시켜 4관능기 모노머인 [(oxybis(methylene)] bis(2-ethylpropane-2,1,3-triyl)tetrakis(oxy)tetrakis(3-oxopropane-3,1-diyl)tetraacrylate (DTMP-CEA)를 합성하였다. 모노머 합성 후 NMR,과 FT-IR 분석을 통해서 화학구조를 확인하였다. DTMP-CEA 모노머는 상업적으로 활용되고 있는 EB-40과 함께 GPC, 점도, 접착성 분석 및 UV 잉크에 적용하여 물성들을 비교하였다. GPC 분석 결과, EB-40은 다양한 분자량을 가진 혼합물로 구성된 반면에, DTMP-CEA는 단일 분자로 이루어져 있음을 확인하였다. Bond shear strength를 측정하였을 때, DTMP-CEA와 EB-40은 각각 725.3 N, 158.3 N으로 개발된 모노머가 약 4.6 배 향상된 결과를 보였다. 또한, 모노머들을 cyan UV 잉크에 적용하였을 때, DTMP-CEA는 10% 이상 빠른 cure speed를 보였다.
