- W1977591175 abstract "주단량체로 에틸 아크릴레이트, 부틸 아크릴레이트, 메톡시에틸 아크릴레이트, 가교 단량체로 글리시딜 메타아크릴레이트를 유화중합하여 아크릴고무를 제조한 후, 가교제로써 2,2-bis[4-(4-aminophenoxy)phenyl]propane를 첨가하여 고무컴파운드를 제조하였다. 주단량체의 조성에서 에틸 아크릴레이트의 함량이 증가하면 내열성이 증가하는 경향을 보였는데 이는 아크릴고무의 유리전이온도가 감소되었기 때문이다. 또한 에틸 아크릴레이트의 에스테르 그룹 농도가 3개의 주단량체 중 가장 높기 때문에 에틸 아크릴레이트 함량이 증가할수록 내유성이 향상되었다. 2,2-Bis[4-(4-aminophenoxy)phenyl]propane의 함유량에 따른 영향은 2 phr 첨가까지 인장강도와 신장율은 증가하지만, 그 이상의 첨가에서는 가교밀도의 증가에 따른 점성과 탄성이 감소하여 그 값들이 감소하였다. Acrylic rubber was synthesized using ethyl acrylate. butyl acrylate, methoxyethyl acrylate as main monomers and glycidyl methacrylate as cure site monomer by emulsion polymerization. Rubber compound was made by adding 2,2-bis[4-(4-aminophenoxy)phenyl]propane as crosslinking agent. Increase of ethyl acrylate content in the main monomer ratio resulted in enhancement of heat resistance due to decrease of glass transition temperature in acrylic rubber. And also oil resistance was increased with increasing content of ethyl acrylate because ethyl acrylate has the highest ester concentration in the three main monomers. With content of 2,2-bis[4-(4-aminophenoxy)phenyl]propane, both tensile strength and elongation were increased until 2 phr, but in higher content than that, they decreased owing to reduction of viscosity and elongation by increase of crosslinking density." @default.
