    • Light emitted from a light source (22) is used through a light projection optical system (23) to perform coaxial down-emission lighting on a measurement target (36). Light reflected by the measurement target (36) is formed on a photo-detector (26) through an image formation optical system (24). Along its optical path, a spectroscope (25) is provided for converting an image impinging on the photo-detector (26) into a spectroscopic image having a predetermined wavelength band. A measurement point extraction portion (32) in a signal processing portion (28) determines a predeterm film thickness measurement point from an image picked up by the photo-detector (26), extracts an image signal at the film thickness measurement point, and transmits t to film thickness operation portion (33).

    • A methyl methacrylate syrup is produced by the steps of (1) preparing a starting material comprising methyl methacrylate or a monomer mixture mainly comprising methyl methacrylate, and dividing the starting material into 20 to 70% by weight of an initial charge and 30 to 80% by weight of an after-charge; (2) heating the initial charge in a reactor; (3) adding a whole protion of a chain transfer agent at the time when the initial charge reaches a reaction temperature; (4) adding the after-charge over 0.1 to 10 hours together with a polymerization initiator having a half-life of 10 to 300 seconds at the reaction temperature; (5) continuing the heating after the addition of the after-charge and the polymerization initiator is complete; and (6) adding a hindered phenol polymerization inhibitor at the time the heating is finished. The methyl methacrylate syrup thus produced is excellent in storage stability.

    • There is disclosed a process for producing a glycidyl ester of acrylic acid or methacrylic acid which comprises the steps of neutralizing acrylic acid or methacrylic acid with a carbonate or a bicarbonate of an alkali metal in an excess amount of epichlorohydrin while an oxygen-containing gas is blown into the liquid reaction system; subjecting water formed by the neutralization and epichlorohydrin to azeotropic distillation to discharge them outside the reaction system and to form an alkali metal salt of acrylic acid or methacrylic acid; adding a quaternary ammonium salt as a catalyst to the reaction system to react the alkali metal salt of the acid with the epichlorohydrin and thus synthesize the glycidyl ester of the acid; cooling the liquid reaction product while recovering part of the excess epichlorohydrin under reduced pressure; adding aqueous solution of an alkali hydroxide to the liquid reaction product to separate into aqueous layer and organic layer; adding a catalyst deactivator to the organic phase; and subsequently distilling the organic layer to separate the glycidyl ester of the acid while blowing an oxygen-containing gas into the organic layer. The above process makes it possible to efficiently produce a highly pure glycidyl ester of acrylic acid or methacrylic acid in high yield with minimized contents of impurities.
