Abstract
Disclosed herein are high refractive index monomers that are curable by ultraviolet light. These monomers may be a component of curable compositions useful in the preparation of optical articles. Also disclosed is a method of synthesizing the monomers.
Claims11
A high refractive index monomer, comprising:
- a compound according to formula (I)
- wherein Z is an ethylenically unsaturated group;
- X is O, S, or NH;
- L1 and L2 are each independently C1-C3 alkylene, —(C1-C3 alkylene)-S—(C1-C3 alkylene)-, or —(C1-C3 alkylene)-O—(C1-C3 alkylene)-;
