• Isocyanato-terminated polysulfide polymers and processes for their preparation

  公开（公告）日：1981-03-18

  Fully and partially arylamine-terminated polysulfide polymers and processes for their preparation and use are disclosed. The fully arylamine-terminated products are curable with polyisocyanates to high molecular weight polymers which are useful in molding and casting as well as in sealants. The partially arylamine-terminated polymers may be further reacted with polyisocyanates to form thiol-terminated polysulfide polymers containing urea chain segments. These compounds are curable in the same manner as standard polysulfide polymers to form firmer polymers. The partially arylamine-terminated polymers may also be chain extended using isocyanate-terminated urethane prepolymers. These block copolymers may be cured by standard SH-terminated polysulfide polymer curing methods to prepare sealants of exceptional resiliency and weather resistance.

  本发明公开了全芳基胺封端和部分芳基胺封端聚硫聚合物及其制备和使用工艺。全芳基胺封端的产品可与多异氰酸酯固化成高分子聚合物，可用于模塑、铸造和密封剂。部分芳基胺封端的聚合物可进一步与多异氰酸酯反应，形成含有脲链段的硫醇封端的多硫化物聚合物。这些化合物的固化方式与标准聚硫聚合物相同，可形成更坚固的聚合物。部分芳基胺封端的聚合物也可以使用异氰酸酯封端的聚氨酯预聚物进行链延伸。这些嵌段共聚物可采用标准的 SH 端聚硫聚合物固化方法进行固化，以制备具有优异回弹性和耐候性的密封剂。

  An ultrathin film composed substantially of silicon-containing polyurea comprising polyaddition bonded units derived from (A) at least one polyamine selected from the group consisting of silicon-containing polyamines and hydrocarbon-type polyamines, each of said polyamines containing at least two primary or secondary amino groups in the molecule, and (B) at least one polyisocyanate compound selected from the group consisting of silicon-containing polyisocyanates and hydrocarbon-type polyisocyanates, each of said polyisocyanates having at least two isocyanate groups in the molecular chains; provided that when the polyisocyanate compound is the hydrocarbon-type polyisocyanate alone, at least one of the selected polyamines is a silicon-containing polyamine containing at least one terminal amino group in the molecule. A composite structure composed of a microporous supporting film and the ultrathin film supported thereon is useful for the production of a gaseous mixture containing a specified gas in a high concentration from a mixture of two or more gases including said specified gas, and is prepared by subjecting the polyamine and the polyisocyanate compound to interfacial polyaddition reaction on a microporous supporting film to form an ultrathin film composed substantially of a silicon-containing polyurea on the microporous supporting film.
