| titleOfInvention | Process for manufacturing a polarized poly(thio)urethane optical lens |
| abstract | The invention relates to a process for manufacturing a polarized poly(thio)urethane-based optical article comprising the steps of disposing a polarizing film or wafer in a molding cavity of a two part mold assembly; pouring a polymerizable composition comprising at least one polyiso(thio)cyanate monomer and at least one polyol and/or polythiol; or a mixture of at least one liquid NCO and/or NCS terminated poly(thio)urethane prepolymer and at least one liquid OH and/or SH terminated poly(thio)urethane prepolymer; with the proviso that the polymerizable composition has a ratio of NH2 functionalities to the NCO or NCS functionalities of less than 0.9; polymerizing the composition under such conditions that a hard gel is obtained in less than 30 minutes; completing the polymerization; and opening the two part mold so as to recover the bubble free optical article. |
