NON-ELASTOMERIC POLYURETHANE COMPOSITIONS |
摘要 |
The present invention relates to a non-elastomeric polyurethane composition which includes a chain extender of general formula (1) wherein R1, R2, R3, R4, R5, and R6, are the same or different and selected from an optionally substituted straight chain, branched or cyclic, saturated or unsaturated hydrocarbon radical; R7 is a divalent linking group or an optionally substituted straight chain, branched or cyclic, saturated or unsaturated hydrocarbon radical; and n is 0 or greater. The non-elastomeric polyurethane composition has improved mechanical properties, clarity and/or degradation resistance and may be used to produce medical devices, articles or implants.
