ABSTRACT:
The invention relates to a method of reducing the inhalation toxicity of functional fluids by incorporating into a functional fluid an effective amount of copolymer which is obtainable by copolymerizing etheylene oxide, propylene oxide and/or butylenes oxide with an initiator monool or diol, said copolymer having a degree of unsaturation of less than about 0.01 meq/g.
