  • Method of indirect liquid-phase heat transfer
    Patent number: 4624299
    Abstract: A method of indirect liquid phase heat transfer which comprises continuously circulating between a heat generating and a heating source or water-soluble or water-dispersible polymer having a viscosity of less than about 100 centistokes at 100.degree. F., of the formula:R(OAR').sub.xwhereinR is a C.sub.5 to C.sub.36 linear branched or alicyclic aliphatic hydrocarbyl group;O is oxygen;A is a polyoxyalkylene residue having oxyalkylene units derived from ethylene oxide or ethylene oxide and at least one other lower alkylene oxide having 3 or 4 carbon atoms;R' is hydrogen, a C.sub.1 to C.sub.8 alkyl group or nonbornyl; andx is an integer having a value of 1 to 6, wherein for values of x greater than 1 each AR' may be the same or different.
