Abstract:
A method for preparation and polymerization of siloxane monomers of Formula I is presented. The synthesis includes the selective reaction between silanol containing unit and alkoxy containing units in the presence of basic catalyst. The siloxane monomers of the invention can be used for preparation of siloxane polymers with good flexibility and cracking threshold, and functional sites, useful for applications requiring low metal content in semiconductor industry.
