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