On the preparation of acrylic acid/vinyl acetate copolymers with constant composition .1. Copolymerization reactivity ratios
In the present work, low conversion acrylic acid (AA)/vinyl acetate (VAc) copolymerizations were carried out in azeotropic ethanol/water solutions containing 93% in weight of ethanol. Reactivity ratios were determined by several methods and shown to be equal to r(AA) = 2.6 and r(VAc) = 0.04. (C) 1997 Elsevier Science Ltd.
