N-vinyl-2-pyrrolidone → Decane

Participants

Reaction Steps

A mixture of 14 g of the resin P-2 obtained in Production Example 2 of dispersion stabilizing resin, 85 g of vinyl acetate, 15 g of N-vinylpyrrolidone, 1.2 g of the macromonomer M-1 obtained in Production Example 1 of macromonomer, and 380 g of n-decane was heated to 75° C. with stirring under nitrogen gas stream. After adding thereto 1.7 g of A.I.B.N., the reaction was carried out for 4 hours and, after further adding thereto 0.5 g of A.I.B.N., the reaction was carried out for 2 hours. After cooling, the reaction mixture was passed through a 200 mesh nylon cloth to obtain a latex having a mean grain size of 0.23 μm as a white dispersion.
