  • Tris-(polyalkoxyalkylated) isocyanurate compounds and their use as functional fluids
    Patent number: 4260505
    Abstract: Novel tris-(polyalkoxyalkylated) isocyanurate compounds are described having the formula: ##STR1## wherein x is an integer from 2-10; Y is either a hydrogen or methyl group; and R is an alkyl group having from 1-4 carbon atoms. The use of these isocyanurate compounds as functional fluids, including hydraulic-type and heat transfer-type fluids, is also described. Such functional fluids have superior fire resistance properties.
