Foamed polymer and process for production thereof |
| abstract |
A foamed isocyanate-based polymer having a cellular structure and comprising a non-surface cross-linked superabsorbent polymer, the foamed polymer being capable of: (i) absorbing at least about 10 times its weight of a 0.9 wt./wt. % aqueous NaCl solution maintained at a temperature of from about 20 DEG to about 25 DEG C., and (ii) retaining at least about 10 times its weight of absorbed aqueous NaCl solution which is bound to the superabsorbent polymer. A process for producing the foamed isocyanate-based polymer is also described. The process comprises the steps of: contacting an isocyanate, an active hydrogen-containing compound, an aqueous blowing agent, a catalyst and a non-surface cross-linked superabsorbent polymer, the superabsorbent polymer being capable of absorbing at least about 10 times its weight of a 0.9 wt./wt. % aqueous NaCl solution maintained at a temperature in the range of from about 20 DEG to about 25 DEG C.; and expanding the reaction mixture to produce the foamed isocyanate-based polymer. The active hydrogen-containing compound comprises from about 10% to 100% by weight of a hydrophilic active hydrogen-containing compound and from 0 to about 90% by weight a non-hydrophilic active hydrogen-containing compound. The foamed isocyanate-based polymer is ideally suitable for use in an absorption layer in a personal hygiene device. |
