New polyurethanes containing 2,5-disubstituted furan rings, useful for preparing flexible foams with surface-bonded active agents for medicinal applications, especially as breast prostheses |
摘要 |
Polyurethane (I) for flexible foam preparation is claimed, where (i) water-foamable (I), containing 2,5-disubstituted furan rings, are synthesized via the conversion of 2,5-bis-(hydroxymethyl)-furan, 5-hydroxymethyl-2-furan-carboxylic acid and/or 2,5-furan-dicarboxylic acid into polyurethane prepolymers and (ii) (I) is surface modified to allow covalent or ionic bonding of active agents.
