    摘要： Aqueous warp sizing compositions and the sized yarns obtained by applying the new sizing composition to textile yarn, removing excess composition from the yarn, drying the resulting wet-sized yarn and separating the individual yarns (ends) from one another before or after drying. The novel aqueous sizing composition is a blend of a lubricant, a surfactant, a redispersible latex composition and various optional ingredients. The redispersible latex component comprises a blend of (a) a six-membered carbocyclic compound having two carboxyl substituents and which is soluble in aqueous alkaline media such as the disodium salt of 1,2,3,6-tetrahydrophthalic acid and (b) an aqueous colloidal dispersion of a film-forming carboxyl-containing polymer such as a copolymer of styrene, butadiene and acrylic acid.

    摘要翻译： 水性经纱施胶组合物和通过将新的施胶组合物施加到纺织纱线上得到的尺寸的纱线，从纱线中除去多余的组合物，干燥所得到的湿尺寸纱线并在干燥之前或之后将各个纱线（末端）彼此分离。 新型水性施胶组合物是润滑剂，表面活性剂，可再分散胶乳组合物和各种任选成分的混合物。 可再分散胶乳组分包含（a）具有两个羧基取代基的六元碳环化合物的共混物，其可溶于碱性水溶液如1,2,3,6-四氢邻苯二甲酸的二钠盐和（b） 成膜性含羧基聚合物如苯乙烯，丁二烯和丙烯酸的共聚物的水性胶体分散体。

    摘要： A NOVEL COMPOUND 2,2'' - BIS(HEPTAFLUOROPROPYL)-5,5''BIBPENXOZOLE AND THE MANNER OF ITS PREPARATION. THE COMPOUND IS PREPARED BY REACTING 3,3''-DIAMINOBIPHENOL IN A SOLVENT OR CARRIER LIQUID WITH METHYLPERFLUOROBUTYRIMIDATE IN THE PRESENCE OF AN ALIPHATIC CARBOXYLIC ACID AS REACTION PROMOTER. ATLTERNATIVELY, THUS COMPOUND CAN BE PREPARED BY HEATING 3,3''-BIS(HEPTALFUOROBUTYRAMIDO)-4,4''DIHYDROXYBIPHENYL IN THE PRESENCE OF A DEHYDRATING AGENT TO EFFECT CYCLIZATION. THE PRESENT NOVEL COMPOUND IS SUITABLE FOR USE AS AN ANTIPLASTICIZER.

THE COMPOUND IS PREPARED BY REACTING 3,3''-DIHYDROXYBENZIDINE IN A SOLVENT OR CARRIER WITH METHYL PERFLUOROBUTYRIMIDATE IN THE PRESENCE OF AN ALIPHATIC CARBOXYLIC ACID AS REACTION PROMOTER. ALTERNATIVELY, THE COMPOUND CAN BE PREPARED BY HEATING, 4,4'' - BIS(HEPTAFLUOROBUTYRAMIDO) -3,3''-DIHYDROXYBIPHENYL IN THE PRESENCE OF A DEHYDRATING AGENT TO EFFECT CYCLIZATION. THE PRESENT NOVEL COMPOUND IS SUITABLE FOR USE AS AN ANTIPLASTICIZER.
