Summary Acidic copolymers of the poly(β-hydroxy-acid) type containing β-malic acid (hydrophilic) and β-malic acid benzyl ester (hydrophobic) repeating units in various proportions are prepared by two differentes routes : — catalytic hydrogenolysis of the benzyl ester bonds of homopoly(β-malic acid benzyl ester) and — chemical coupling of benzyl alcohol to poly(β-malic acid). In attempts to account for the route-dependence of the physico-chemical properties of resulting copolymers, GPC in aqueous medium and measurements of the solubility of Yellow OB, a lipophilic dye, in aqueous solutions have been carried out. The results are discussed in regard to the sequence distributions of hydrophilic and hydrophobic repeating units.
