반응 단계
73.5 parts by weight of maleic anhydride and 21.4 parts by weight of vinyl acetate were dissolved in 240 parts by volume of xylene and heated to 70° C. 4.5 parts by weight of ditertiary butyl peroxide in 20 parts by volume of xylene were added and the reaction mixture was heated to 130° C. and maintained at this temperature for 3 hours. A brown resin precipitated, which on cooling solidified, and was easily separated from the bulk of the xylene by decantation. Yield = 87% (on weight of monomers). The number average molecular weight of the polymer by vapour phase osmometry was found to be 675.
