Abstract

In order to select the best compatibilizer for PE/asphalts mixtures, compatibilities of poly(ethylene-co-acrylic acid) and poly(ethylene-co-methacrylic acid) based ionomers with asphalts were investigated via optical microscopy, thermal analysis and rheology. By comparing the polarities of ionomers through an ultimate adsorption of moisture, it was observed that the compatibilities of ionomers increase with the increases of the polarities. By rheological investigations, some of ionomer were observed to be not only compatible but also miscible with asphalts.

아스팔트와 PE 혼합물에 사용될 상용화제를 선정하기 위하여 poly(ethylene-co-acrylic acid)와 poly(ethylene-co-methacrylic acid)의 금속염인 이오노머들의 아스팔트에 대한 상용성을 광학 현미경, 열분석 및 유변학 연구를 통하여 관찰하였다. 수분 흡수를 통한 극성 분석, 광학 현미경 관찰 결과와 열분석을 통하여 후보 고분자들의 아스팔트와의 상용성을 관찰한 결과 대체적으로 극성이 높을수록 아스팔트와의 상용성이 높아짐을 알 수 있었다. 또한 유변학 관찰을 통하여 몇몇 고분자들은 아스팔트와 균일 상을 이룬다는 것을 알 수 있었다.
