  This invention relates to a polyisocyanate prepolymer for polyurethane and polyurethane/urea elastomer synthesis and to the resulting elastomer. The prepolymer is formed by reacting a cyclohexanediisocyanate with a long chain polyol under conditions such that essentially a 2:1 adduct is formed. Excess cyclohexanediisocyanate is removed prior to forming the elastomer.

  本发明涉及一种用于聚氨酯和聚氨酯/尿素弹性体合成的多异氰酸酯预聚物，以及由此产生的弹性体。这种预聚物是通过环己烷二异氰酸酯与长链多元醇在基本上形成 2:1 加合物的条件下发生反应而形成的。在形成弹性体之前，多余的环己烷二异氰酸酯会被去除。

  Water-soluble polyurethane according to the present invention is obtained from polyalkylene glycols, diisocyanates, and comb-shaped hydrophobic diols represented by the following general formula (3): 1 wherein each of R 1 , R 2 and R 3 is a hydrocarbon group; each of Y and Y′ is hydrogen, a methyl group or a CH 2 Cl group; each of Z and Z′ is oxygen, sulfur or a CH 2 group; n is an integer of 0 to 15 when Z is oxygen and is 0 when Z is sulfur or a CH 2 group; n′ is an integer of 0 to 15 when Z′ is oxygen and is 0 when Z′ is sulfur or a CH 2 group. The water-soluble polyurethane is used as, for example, an extruding auxiliary for cement materials, a mortar thickening agent, an underwater concrete thickening agent, a ceramics forming binder and a moisturizer for hair cosmetics, all of which are characterized by excellent water retention and high shape retention.

  根据本发明，水溶性聚氨酯由聚亚烷基二醇、二异氰酸酯和梳状疏水二元醇制得，其通式（3）如下： 1 其中每个 R 1 , R 2 和 R 3 是烃基；Y 和 Y′各自是氢、甲基或 CH 2 Cl基团；Z和Z′各自为氧、硫或CH 2 当 Z 为氧时，n 为 0 至 15 的整数，当 Z 为硫或 CH 2 Cl 基团时，n 为 0。 2 当 Z′为氧时，n 为 0 至 15 的整数，当 Z′为硫或 CH 2 基团时，n 为 0。 2 基团时为 0。 水溶性聚氨酯可用作水泥材料的挤出助剂、砂浆增稠剂、水下混凝土增稠剂、陶瓷成型粘结剂和头发化妆品保湿剂等，所有这些产品的特点都是保水性好、保形性高。
