摘要： The invention pertains to an improved branched glycolic acid polymer being obtained from polycondensation reaction of a monomer mixture comprising: (i) glycolic acid (GA); (ii) optionally, at least one hydroxyacid having only one hydroxyl group and only one carboxylic acid group different from GA [hydroxyacid (A)], wherein the molar amount of hydroxyacid (A) is of at most 5 % moles with respect to the sum of moles of GA and hydroxyacid (A); (iii) at least one polyol comprising at least three hydroxyl groups and being free from carboxylic acid group [polyol (H)]; (iv) at least one alcohol comprising one or two hydroxyl groups and being free from carboxylic acid group [alcohol (AO)]; (v) optionally at least one carboxylic acid comprising one carboxylic acid group and being free from hydroxyl group [monoacid (C)]; and (vi) optionally at least one polyacid comprising at least two carboxylic acid groups and being free from hydroxyl groups [polyacid (O)], wherein the amount of polyacid (O) is such that the number of carboxylic acid groups thereof is comprised between 0.025 and 0.900 % with respect to the overall number of hydroxyl groups of glycolid acid and of the hydroxyacid (A), if present.
