Abstract
Process for obtaining a polyester, characterized in that it comprises heating at least one anhydride or dicarboxylic acid, alpha-beta-unsaturated, or a mixture of anhydrides or dicarboxylic acids containing at least 10 mole% of anhydride or dicarboxylic acid , alpha-beta-unsaturated, with propylene oxide, ethylene oxide, butylene oxide or mixtures thereof, in the presence of a catalytic amount of a lithium compound, until a reaction product of an acid number of 20 is obtained. about 130 and then maintaining said product at a temperature of about 200º C to about 240º C for a period of 30 minutes to 6 hours.
