Abstract
Disclosed is a composition based on copolymers including at least one A-B block copolymer, wherein block A is a polyester and block B is a polyoxyethylene (PEG), and wherein the total molecular mass in weight of the PEG is higher than or equal to 50 kDa, and the ethylene oxide motif/ester motif molar ratio is between 0.5 and 5. The invention also relates to an anti-adhesive material including such a composition, used for the prevention of tissue adhesions and especially for the prevention of intrauterine synechiae.
