| titleOfInvention | METHOD FOR PREPARING AN OPTICAL POLYMERIZED. |
| abstract | The present invention relates to a novel method for preparing a polymerized, which includes the step of polymerizing a two component composition, which includes: a first component containing at least one polycyanate reagent having at least two functional groups which are selected from isocyanate isothiocyanate and combinations thereof, the polycyanate reagent is the reaction product of: a polythiol monomer having at least two thiol groups; and a polycyanate monomer that has at least two functional groups that are selected from isocyanate, isothiocyanate and combinations thereof; and a second component that contains at least one polyamine reagent that has at least two functional groups that are selected from primary amine, secondary amine and combinations thereof. The molar equivalent ratio of groups (NCO + NCS) of the first component to groups (-NH2 + -NH-) of the second component is 0.5 to 100. The present invention also relates to polymerized preparations according to the method of the present invention. The present invention is further related to photochromic articles that can be prepared from the polymerized of the present invention. |
