SECOND GENERATION HYBRID SILANE MODIFIED POLYMERS OF LOW VISCOSITY FOR LOW TOXICITY RTV SEALANTS AND ADHESIVES

摘要

The present method relates to the production of alcoxysilane capped polymers, as well as the production of sealants and adhesive using the alcoxysilane capped polymers formed from the present method. The method of production results in final alcoxysilane capped polymers that have a low viscosity and are safer for manufacturers, and end users.

主权项

1. A method for manufacturing alcoxysilane capped polymers, the method comprising:
creating a polymeric composition by mixing polypropylene glycol, HDI, a polymer catalyst, and isosilane; and adding vinyl silane and methanol to reduce the viscosity of the polymeric composition.
