초록

폴리프로필렌(PP)과 에틸렌-프로필렌-디엔 공중합체(EPDM) 블렌드의 열적성실과 결정구조에 미치는 이오노머 첨가의 영향에 대해 시차주사열량계(DSC), 레오미터(RDS) 및 X-선회절계를 사용하여 연구하였다. PP와 EPDM의 조성은 중량비고 50/50으로 고정하였고 중화금속이 다른 두 종류(Na⁺ 및 Zn⁺⁺)의 이오노머를 5-20wt.% 사용하였다.PP/EPDM 블렌드의 열적성질과 결정구조는 Zn⁺⁺으로 중화된 이오노머의 첨가에는 크게 영향을 받지 않았으나 Na⁺로 중화된 이오노머의 첨가에는 크게 영향을 받았으며 특히 5 wt.%가 첨가될 때 그 영향이 가장 크게 나타났다.

The effect of ionomer addition on the thermal properties and crystalline structure of a polypropylene(PP)/ethylene-propylene-diene terpolymer(EPDM) blend was investigated by using Rheometric dynamic spectrometer(RDS), differential scanning calorimeter(DSC), and X-ray diffractometer. Two kinds of poly(ethylene-co-methacrylic acid) ionomers containing different metal ions(Na⁺ and Zn⁺⁺) were compared to find out the effects of the metal ion type for neutralization and the ionomer contents. The composition of PP and EPDM was fixed at 50/50 by weight and the ionomer contents varied from 5 to 20 wt.% It was found that the thermal behavior and crystalline structure of the PP50-EP50 blend were not affected by the addition of Zn-neutralized ionomer but significantly affected by the addition of Na-neutralized ionomer. The effect of adding Na-neutralized ionomer to PP50-EP50 blend was most prominent at the concentration of 5wt %.

Keywords:PP/EPDM blend;ionomer;crystal structure;thermal property
