Abstract
The present invention relates to novel silanes of the formula Si(R<sup>1</sup>)<sub>m</sub>(R<sup>2</sup>)<sub>4-m</sub>, wherein each R<sup>1</sup> independently stands for a substituted or unsubstituted alkyl, alkenyl, or alkynyl group; a substituted or unsubstituted cycloaliphatic group or aryl group; a substituted or unsubstituted heteroalicyclic group or heteroaryl group; each R<sup>2</sup> independently stands for a group of the general formula -O-CHR<sup>3</sup>-C(=O)-OR<sup>4</sup>, wherein R<sup>3</sup> independently stands for: a substituted or unsubstituted alkenyl group, preferably vinyl or allyl group; R<sup>4</sup> stands for: a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heterocyclyl or heteroaryl group; and m independently stands for 0 or 1, preferably 1. The invention also relates to curable compositions containing said silane and a curable polyorganosiloxane endcapped with such silanes. The silane acts as a crosslinker in the curable compositions and is notable particularly for being obtainable from renewable resources, providing for a high overall performance.
