• Isocyanato-terminated polysulfide polymers and processes for their preparation

  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。

  Polysilazane addition polymers are prepared by (1) reacting ammonia with one or more halogenated organic silicon compounds to produce a cyclic silazane ammonolysis product and (2) reacting the ammonolysis product with from 0.1% to 30% by weight of an isocyanate, isothiocyanate, ketene, thioketene, carbodiimide, or carbon disulfide. Polysilazane addition polymers containing alkenyl or alkynyl groups can be cured by supplying energy to generate free radicals. The cured or uncured polymers can be pyrolyzed to produce silicon nitride-containing ceramic materials.
