S-ALKYL THIOCARBAMATE BASE RESIN, PLASTIC LENS COMPRISING THE RESIN, AND PROCESS FOR MAKING THE LENS |
摘要 |
Disclosed herein are a novel and highly refractive S-alkyl thiocarbamate base resin useful in preparing lenses and a process for producing the resin comprising reacting one or more polyisocyanate compounds and one or more mercapto compounds having at least one hydroxy group, a plastic lens made of the resin, and a process for making a plastic lens of high profile regularity from the resin by using internal mold releasing agents in the casting polymerization process. |
