Beschreibung
Zusammenfassung:	The present invention provides moisture-curable polymeric compositions, overcoming disadvantages normally associated with moisture-curable polymeric compositions, a process for their preparation, and methods of use thereof. The process included in the present invention ensures full end-capping. Furthermore, the present invention makes use of diisocyanates to chain-extend polyether polyols to a desired length. This allows the process of the present invention to accommodate a wide range of polyether polyols in the synthesis of the compounds of the invention. Additionally, the process of the present invention reduces the level of unreacted isocyanate to an acceptable level of approximately 0.1 wt %.
