ABSTRACT:
A method of making a photochromic polysiloxane includes the steps of forming a photochromic spironaphthooxazine monomer including an alkene terminated side and, by addition reaction, covalently bonding the alkene carbon to [SiH] moieties of a siloxane polymer. Novel spironaphthooxazine monomers and photochromic polysiloxanes are disclosed.
