  The present invention is directed to solubilizing compounds, a device and a method for solubilizing and removing carboxylic acids and especially fatty acids from oils, fats, aqueous emulsion, aqueous media and organic solutions. Devices utilizing the inventive method shall be used for separating carboxylic acids from oils, fats, aqueous emulsion, lipophilic media or organic solutions, respectively by preparing an aqueous micro- or nanoemulsion of the carboxylic acids especially the fatty acids and the solubilizing compound which contains at least one amidino and/or gianidino group. Solubilization effects of solubilizing compounds combined with the inventive use of separation methods for carboxylic acids can be used to treat persons in need of removal of fatty acids or analyze carboxylic acids from blood or process other solutions in food, pharmacy, chemistry, bio fuel industry or other industrial processings.

  A polyamide and/or polyimide is prepared by using N,N'- dimethylethyleneurea or N,N'-dimethylpropyleneurea as a solvent for polycondensation of a polycarboxylic acid and a diisocyanate at a temperature above 100°C in the presence of an alkali metal carbonate, alkali metal hydrogencarbonate, alkali metal hydroxide or an alkali metal salt of a polycarboxylic acid. Where an alkali metal salt of a polycarboxylic acid is employed, the salt is preferably of an acid having the same or a similar structure to the polycarboxylic acid participating in the polycondensation reaction.

  以 N,N'-二甲基亚乙基脲或 N,N'-二甲基丙基脲为溶剂，在碱金属碳酸盐、碱金属碳酸氢盐、碱金属氢氧化物或聚羧酸的碱金属盐存在下，在 100°C 以上的温度下进行聚羧酸和二异氰酸酯的缩聚反应，制备聚酰胺和/或聚酰亚胺。 在使用聚羧酸的碱金属盐时，盐最好是与参与缩聚反应的聚羧酸具有相同或相似结构的酸。

  The present invention pertains to compositions containing a polycondensate derived from a dicarboxylic acid component, a diol component and an ethylenically unsaturated dicarboxylic acid component. Said composition may be crosslinked to yield an adhesive composition. The adhesive composition of the invention may be used for tapes and patches in the medical field, but also for non-medical applications such as masking tapes, protective tapes and for bonding of semiconductor elements. The adhesive composition of the invention may be irradiated to thereby reduce the adhesive strength in a controlled manner.
