  The invention relates to a degradable polymer and a process for preparing of the degradable polymer which has a structure resulting from combination of a star-shaped polymer comprising a polyfunctional center compound of polycarboxylic acid having three or more carboxyl groups and/or anhydride of the same or aliphatic polyhydric alcohol having three or more hydroxyl groups and a unit of aliphatic hydroxycarboxylic acid, through aliphatic polyhydric alcohol having two or more hydroxyl groups or polycarboxylic acid having two or more carboxyl groups or anhydrides of the same. The degradable polymer of the invention leads to remarkably low coloration as compared with a polymer comprising polysaccharide as a polyfunctional center compound, has high melt tension as compared to common aliphatic polyester is excellent in processability on various molding methods, foam molding and blow molding in particular, and high transparency.
