It is observed that in a refrigerator the refrigeratory plate coated with polyethylene glycol is hardly frosted, and that the surface of ice, when contacted with polyethylene glycol, melts gradually even at a temperature as low as below -5°C.<BR>These phenomena are largely ascribed to the molecular weight of polyethylene glycol. When the molecular weight of polyethylene glycol used is 1020, the interface between ice and polyethylene glycol melts even at -14°C.<BR>It is considered that ether groups of polyethylene glycol play important parts in these phenomena.
