Abstract
The present invention relates to novel amine terminated cycloaliphatic polysiloxanes, and preparations thereof. More particularly, the invention provides several reaction schemes for the synthesis of amino-functionalized cyclo-aliphatic silicones and the products produced by the reaction schemes. In one embodiment of the invention, an amine functionalized silicone is prepared through a base-catalyzed ring-opening reaction. In another embodiment of the invention, an amine functionalized silicone is prepared through the hydrosilation of a silicone oligomer through the blocking and deblocking of an amine terminated in a vinyl group.
