Abstract
The present disclosure relates to the process of making a photochromic composite having a photochromic polymer and a binder polymer. The photochromic polymer is made by solution polymerization of the photochromic monomer and two monomers in the presence of a base and the binder polymer is made by solution polymerization of the two monomers in the presence of a base.
