Polyurethane or polyurethane-urea elastomeric compositions |
| abstract |
Polyurethane or polyurethene-urea elastomer composition characterized in that it is a reaction product of (A) a flexible segment macrodiol which is either (i) a homopolymer corresponding to the formula (I), HO - [(CH2) nO] mH in which n represents an integer greater than 5 and less than 13, m is a number such that the weight-average molecular weight of the compound of formula (I) is between 218 and 5000, and at least one atom of hydrogen represented in formula (I) is optionally substituted by a C1-3 alkyl group or by a halogen atom; or (ii) a copolymer containing at least 25% by weight of repeat units of - (CH2) nO- where n is as defined above; or (iii) a mixture of macrodiols of which at least 10% consists of a macrodiol as defined above; (B) an aliphatic or aromatic diisocyanate known from the polyurethane manufacturing technique; and (C) optionally a chain extender. A biomaterial and a device for medical use are also provided, made entirely or partially of said polyurethane or polyurethane-urea elastomer composition. |
