PURPOSE:To obtain the title cold reserving material, readily producible, having proper flexibility even at low temperature, excellent feeling in use, excellent shape retention and cold reserving properties, by blending liquid rubber containing plural isocyanate groups with a hydrous hydrogel and dispersing. CONSTITUTION:(A) 100 pts.wt. rubber (preferably 1,000-5,000 molecular weight), (semi)liquid at normal temperature, containing two or more isocyanate groups in the molecule (preferably at the ends) is blended with (B) 50-1,000 pts.wt. hydrous hydrogel having preferably 80-95wt.% water content and dispersed to give the objective cold reserving material. |
