Methacrylic Acid → Benzoyl Peroxide

Participants

Reaction Steps

Subsequently, 100 parts of the resin (VIB-3) was fed into a same reaction vessel replaced with nitrogen, followed by elevating a temperature to 75° C. while agitating. There was added dropwise a mixture composed of 15.4 parts of methacrylic acid, 23.3 parts of styrene, 22.4 parts of isobutyl methacrylate, 5.5 parts of 2-hydroxyethyl methacrylate, 50.1 parts of the -caprolactone-modified acrylic monomer obtained in the Reference Example 3, 9.3 parts of “Niper BW” [benzoyl peroxide manufactured by Nihon Yushi, Ltd.], and 116.7 parts of ethyl acetate over 4 hours to allow to conduct a polymerization reaction. Also after that, agitation was allowed to continue over 4 hours to obtain a vinyl-based copolymer (VIA-5). Nonvolatile components were 48.6%.
