    摘要： A polyamide co-polymer polyol made by the reaction of a dicarboxylic acid diester with a diamine in the presence of a polyether polyol is described. The nylon formed should be present in the polyol in an amount of from 1 to 30 wt. %. The polyether polyol may have a molecular weight of about 2,000 to 8,000. This polyamide co-polymer polyol may be used in the manufacture of elastomers and flexible polyurethane foams which are characterized by good load bearing properties.

    摘要： A process for preparing a polyurea reaction injection molded (RIM) elastomer is described. A hindered polyetherpolyamine is first obtained by reacting a polyol having two or more hydroxyl groups with an effective amount of long chain alkyl epoxide to give an at least partially hindered intermediate having hydroxyl terminations; and then aminating at least one of the hydroxyl terminations on the intermediate to primary amine groups to give an at least partially hindered polyetherpolyamine. The hindered polyetherpolyamine is then reacted with a polyisocyanate in the optional presence of a catalyst to give a polyurea RIM elastomer. The long chain alkyl group provides steric hindrance to the primary aliphatic amine group, which slows down the reactivity of the amine. The slower reactivity of the amine group is useful in RIM and RRIM compositions since it allows for longer shot or flow times, which in turn permit larger parts to be made from existing equipment.

    摘要翻译： 描述了制备聚脲反应注射成型（RIM）弹性体的方法。 首先通过使具有两个或多个羟基的多元醇与有效量的长链烷基环氧化物反应得到受阻聚醚多胺，得到具有羟基末端的至少部分受阻的中间体; 然后胺化中间体至伯胺基团上的至少一个羟基端基，得到至少部分受阻的聚醚多胺。 然后在任选的催化剂存在下，将受阻聚醚多胺与多异氰酸酯反应，得到聚脲RIM弹性体。 长链烷基对主要脂族胺基提供空间位阻，这减慢了胺的反应性。 胺基的较慢反应性在RIM和RRIM组合物中是有用的，因为它允许更长的喷射或流动时间，这又允许从现有设备制造更大的部件。

    摘要： N-butylmorpholine and N,N'-dimethylpiperazine may be used together as a catalyst system in an activator solution to give finer, more uniform cells to polyester-based polyurethane foams if a solvent is employed. It was surprisingly discovered that the components must be used together as a catalyst-solvent system to avoid the disadvantages observed when one of the components is changed or left out. For example, if the solvent were not present in the activator solution in proportions of at least 1 wt. %, the activator solution would not be homogeneous.
