Abstract
Based on data in the literature, the washing abilities of block copolymers of ethylene and propylene oxides were correlated with some of their physico‐chemical properties. Quantitative relations correlating washing abilities against clay or coal dirts with surface and interfacial tensions, the cloud point and the melting temperature were obtained. These results show that good washing properties in the considered system were obtained from block copolymers with the following characteristics: surface tension for c = 0.1% below 40 dyne . cm^1^; cloud point near 100°C; and melting point below 30°C. The paper shows the possibilities of using modern statistical methods to obtain the optimal solutions to different technical problems.
