SOFTENING NON-SWELLING POLYURETHANE |
| 摘要 |
A non-yellowing, elastomeric polyurethane is made from a non-aromatic diisocyanate, a diol chain extender, a polyglycol and an aminodiol chain extender. The polyurethane is stable to sterilizing radiation, is made without any processing aids or toxic catalysts, and softens without swelling up to 95% when contacted with an aqueous liquid.
