反応手順

A flask equipped with an agitator, condenser, nitrogen inlet tube and an addition funnel was charged with isooctyl acrylate (155.75 g), N-vinyl-2-pyrrolidone (15.75 g) and hydroxyethyl acrylate (3.50 g) premixed in a mixture of ethyl acetate (249.38 g) and methanol (13.13 g). 2,2'-Azobis-(2-methyl-butyronitrile) (0.26 g, Wako™ V-59) was added to initiate reaction. The mixture was purged with nitrogen to remove oxygen. The mixture was agitated and heated to 57° C. and the reaction was run for about 24 hours at this temperature. After termination of the reaction additional ethyl acetate (178.13 g) and methanol (9.38 g) were added. The inherent viscosity was 1.27 dl/g.
