Enzyme-catalyzed polycondensate method production and adhesive composition

A polycondensate obtainable by reacting: (a) a carboxyl-terminated oligomeric condensation product of (a1) a polyol comprising at least three hydroxyl groups, wherein at least two of these hydroxyl groups are primary hydroxyl groups, and (a2) a dicarboxylic acid, and (b) a diol, comprising two primary hydroxyl groups, wherein the condensation reaction between (a) and (b) is catalyzed by an enzyme. Furthermore, the present invention provides a method of producing such a polycondensate and adhesive compositions comprising said polycondensate.
