Abstract: The present invention relates to a process for producing a resin useful in plastic lenses, to plastic lenses containing the resin and to a process for producing the lenses. The resin is produced from reaction of one or more isothiocyanate compounds with one or more active hydrogen containing compounds selected from polyol compounds, polythiol compounds and hydroxy compounds containing mercapto group. Lenses are produced by casting polymerization.

Abstract: 4-Ethyl-3-(phenyl)-1-(3-trifluoromethylphenyl)-2-pyrrolidinones (I) and corresponding compounds bearing a p-substituent on the 1-position phenyl group and/or a substituent on the 3-position phenyl group exhibit selective herbicidal activities against various weeds which cause problems in rice or upland fields, even at extremely low application rates. They can be prepared by reductive dehalogenation of a corresponding alpha -haloethyl substituted pyrrolidinone or reductive cyclization of a corresponding N-2-butenyl-N-(substituted phenyl)-haloacetyl-3-trifluoromethylaniline. y
