An innovative enzymatic polycondensation of dicarboxylic acids and dialcohols in aqueous polymerization media using free immobilized lipases was developed. Various parameters (type lipases, temperature, pH, stirring type rate, monomer carbon chain length) the an oil-in-water (o/w) miniemulsion (>80% water) were evaluated. The best results for achieved with equimolar concentration (0.5 M) oct...
