| 摘要 |
The invention concerns: biocompatible diphasic compositions, comprising a dispersed phase suspended in a continuous phase; a method for preparing said compositions; a filling material, useful in reparative and plastic surgery based on said diphasic compositions. The invention is characterised in that said diphasic composition dispersed phase consists of particles of at least a (co)polymer hydrogel obtained by polymerising and crosslinking acrylic acid and/or methacrylic acid and/or at least a derivative of said acids. Advantageously, said diphasic composition continuous phase is a polymer hydrogel selected among hyaluronic acid, its salts and a mixture of its salts, advantageously consisting of a sodium hyaluronate, said polymer being crosslinked.
