tert-Butyl methacrylate → HCID 86629093, compound

Participants

Reaction Steps

4-Acetoxystyrene (29.19 g, 0.180 mol), 14.93 g (0.105 mol) of tert-butyl methacrylate, 2.43 g (0.015 mol) of methyl p-vinylbenzoate and 3.45 g (0.015 mol) of polymerization initiator V-601 (produced by Wako Pure Chemical Industries, Ltd.) were dissolved in 148.99 g of cyclohexanone. Subsequently, 37.25 g of cyclohexanone was charged into a reaction vessel, and the solution above was added dropwise to the system at 80° C. in a nitrogen gas atmosphere over 6 hours. After the completion of dropwise addition, the reaction solution was heated with stirring for 2 hours, then allowed to cool to room temperature and added dropwise in 2.5 L of hexane to precipitate a polymer, followed by filtration. The solid collected by filtration was washed by splashing with 500 mL of hexane and then dried under reduced pressure to obtain 41.40 g of a 4-acetoxystyrene/tert-butyl methacrylate/methyl p-vinylbenzoate copolymer.
