The solubility of terpolymers containing alkyl, and perfluoroalkyl side chains as well as succinic acid moieties in the main chain, P[RMA--RMA--MAH] (R = C₄H₉- or CH-, R- = CH₄F-) with ca. 20 mol % fluorinated side chains and 10⁻22 mol % of succinic anhydride rings was tested in a number of solvents varying from water to non polar mineral oils. The polymers are well soluble in fluorinated solvents like Freon-113 and 1,3-bis(trifluoromethyl) benzene, in semi-polar solvents like chloroform, THF or lower esters and also in hydrocarbons with polymers containing dodecyl methacrylate. In self-emulsification experiments, a stable water emulsion of P[F8H2MA--BMA--MAH] was obtained. The dispersability and emulsification of these polymers in mixtures of organic solvents and water yielded stable emulsions in the presence of additional surfactant. Thin films coated from organic solutions as well as from emulsions on glass resulted in water and oil-repelling surfaces with contact angles up to 140° against water and 71° against hexadecane. An enhancing effect of annealing was not observed.
测试了主链含有烷基、全氟烷基侧链以及琥珀酸部分的三元共聚物P[RMA-RMA-MAH](R = C₄H₉-或CH-,R- = CH₄F-)在从水到非极性矿物油等多种溶剂中的溶解度,其中氟化侧链含量约为20 mol%,琥珀酸酐环含量为10⁻22 mol%。这些聚合物可很好地溶解于氟化溶剂如氟利昂-113和1,3-双(三氟甲基)苯中,也可溶解于半极性溶剂如氯仿、四氢呋喃或低级酯中,还能溶解于含有甲基丙烯酸十二酯的聚合物的烃类溶剂中。在自乳化实验中,获得了P[F8H2MA-BMA-MAH]的稳定水乳液。在额外表面活性剂存在的情况下,这些聚合物在有机溶剂和水的混合物中的分散性和乳化性产生了稳定的乳液。从有机溶液以及乳液涂覆在玻璃上的薄膜形成了拒水和拒油表面,与水的接触角高达140°,与十六烷的接触角为71°。未观察到退火的增强效果。
