1. A method for removing heat from a fluid comprising circulating a fluid through crystalline polyethylene silane-grafted-crosslinked polymer pieces crosslinked to retain at least 70% of the heat of fusion of the uncrosslinked crystalline polymer and sufficiently crosslinked for the pieces not to stick together upon being cycled above and below the melting point of said polymer, said fluid having a temperature above the melting point of said polymer.
