Foamed polyurethane polymers for the regeneration of connective tissue |
| abstract |
Process for the preparation of polymeric or copolymeric polyurethane foams with improved hydrophilicity, which involves the use of a catalyst for the crosslinking reaction and a catalyst for the foam formation reaction, comprising the following steps in sequence: a) providing a solution of a polyol or a mixture of polyols in a solvent or a mixture of solvents, in which the solvent is a high-boiling polar aprotic solvent having a boiling point at least 15 °C higher than the softening temperature of the polyols used, that is, the temperature at which the polyols begin to change their state of aggregation from solid to liquid, and a Snyder polarity index P greater than or equal to 5.5, determining the softening temperature and the index Snyder P polarity as indicated in the specification; b) heating the solution of step a) to a temperature higher than the softening temperature of said polyols; c) optionally adding an organic or inorganic filler material; d) adding to the mixture of step c) an aliphatic polyisocyanate or a mixture of aliphatic polyisocyanates; e) adding to the mixture of step d) a porogenic additive; f) adding to the mixture in step e) simultaneously a crosslinking catalyst for polyols with polyisocyanates and a foaming catalyst to form a polymeric or copolymeric polyurethane foam; g) isolating the polymeric or copolymeric polyurethane foam produced in step f). |
