벤톤-폴리에틸렌 및 벤톤-폴리프로필렌을 적당한 온도에서 광유에 분산시키므로써 점토-고분자를 농조제로 사용한 그리이스를 만들었으며, 내마모성, 내수성, 산화안정성, 혼화안정성 및 직점등의 그리이스의 물성을 측정하였다. 그리이스의 성질중 내수성과 같이, 좋지 못한 성질이 간혹 나왔으나 이들 그리이스의 성상을, 이 실험에서 만든 점토-금속비누 그리이스의 성상과 비교 검토할 때 특수목적에 쓸 수 있음을 알았다.
Clay-polymer thickened greases were made by dispersing bentone-polyethylene and bentone-atactic polypropylene into mineral oil at an adequate temperature, and the physical properties such as wear and water washout characteristics, oxidation and shear stabilities, and dropping point of the greases were tested. Even if the greases failed to meet some properties, it was found that those greases can be used for some special purposes, by observing and comparing the properties with those of clay-metallic soap thickened greases that were made in this experiment.
