Abstract
A process for end capping and chain extending silanol terminated polydiorganosiloxanes with a mixture of one or more alkylacetoxydialkoxysilanes and one or more alkyldiacetoxyalkoxysilanes. The resulting capped polymeric material may be utilised as a polymer in e.g. a one-part alkoxy sealant composition such as, for example, an alkoxy low modulus clean (non-staining) or clear sealant composition.
