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.
Claims20
A process comprising:
- contacting a first monomer with at least one photochromic monomer in a first solvent in the presence of a first base to form at least one polymer precursor;
- and
- contacting a second monomer with the at least one polymer precursor in a second solvent in the presence of a second base to form a photochromic polymer.
A process comprising:
- contacting a first monomer with a photochromic monomer in a first solvent in the presence of a first base to form a polymer precursor;
- contacting a second monomer with the polymer precursor in a second solvent in the presence of a second base to form a photochromic polymer;
- forming a binder polymer from the first monomer and the second monomer;
- and
- combining the photochromic polymer and the binder polymer to form a photochromic composite.
