| 摘要 |
The invention relates to the use of copolymers of racemic lactide and epsilon -caprolactone, delta -valerolactone, gamma-decalactone or beta -hydroxybutyric acid, prepared by the reaction of the monomers in the molar ratio of lactide to reaction partner of approximately 95-70 to 5-30, with the addition of metal carboxylates, known per se, as initiators at temperatures of approximately 150 DEG C. over a period of time of approximately 16 to 18 hours, for the topical treatment of human or animal skin.
