Photochromic polyesters and methods of producing photochromic polyesters |
| abstract |
A method for producing a photochromic polyester, the method including: a) providing a reaction solution having at least one ester monomer, a photochromic compound having or functionalized to have at least one hydroxyl group, and a metal-free catalyst; b) reacting the at least one ester monomer and the photochromic compound using the metal-free catalyst to produce a polymeric product, where the polymeric product has a photochromic polyester; and c) separating the polymeric product from the reaction solution. A photochromic polyester includes a photochromic compound covalently linked to a polyester and the polyester is obtained by polymerizing a lactone. |
