  • Photochromic polymer and composition comprising photochromic polymer
    Patent number: 8865029
    Abstract: A photochromic polymer comprising at least one siloxane oligomer and at least two photochromic groups covalently linked to one or both terminuses of the siloxane oligomer and compositions containing photochromic siloxane polymers with narrow polydispersity. The photochromic polymer enhances switching speed in rigid host polymers.
