The invention relates to novel copolylactides which have been polymerized from units of racemic lactide and the comonomers epsi-caprolactone, delta-valerolactone, 1,4-dioxan-2-one or 1,3-dioxan-2-one in a lactide/comonomer molar ratio of 90-80/10-20 in the presence of tin(II) di(ethylhexanoate) as initiator and of a cocatalyst at about 160° C., and have a glass transition temperature between 30 and 43° C., a molecular weight Mn of from 15,000 to 50,000 and a polydispersity Pn (Mw/Mn) between 1.2 and 2. The novel copolylactides are particularly suitable in an outstanding manner for the management of all types of wounds.
