Abstract

PURPOSE: To obtain a heating medium for low temperature insulation, consisting of particulate gels obtained by adding a specific particulate water-absorbing resin powder of crosslinked maleic anhydride copolymer to an aqueous solution of a polyhydric alcohol, and having improved low temperature insulating property and flexibility.
CONSTITUTION: (A) A copolymer prepared from a monomer consisting of a 2W12C α-olefin and/or a vinyl compound with maleic anhydride at a molar ratio of 1W3/1 neutralized with an alkali is partially crosslinked with (B) a crosslinking agent consisting of a polyfunctional epoxy compound and/or polyfunctional amine to give a water-absorbing resin. 1W20wt% resultant resin pulverized into a particulate powder of particle size preferably ≤4 mesh is then added to 5W50pts.wt. aqueous solution of a polyhydric alcohol, e.g. ethylene glycol, with stirring to afford particulate gels, which are then used as a heating medium for low temperature insulation. The copolymer in the component (A) preferably has an intrinsic viscosity of 0.1W 8dl/g (in DMF at 30°C).
