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: EQU R(OAR').sub.x wherein PA1 R is a C.sub.5 to C.sub.36 linear branched or alicyclic aliphatic hydrocarbyl group; PA1 O is oxygen; PA1 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; PA1 R' is hydrogen, a C.sub.1 to C.sub.8 alkyl group or nonbornyl; and PA1 x 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.
