Title:
TRIBLOCK POLYALKYLENE GLYCOLS FOR TWO PHASE LUBRICANTS
Document Type and Number:
WIPO Patent Application WO/2023/159376
Kind Code:
A1
Abstract:
A composition of matter that exhibits two phases at lower temperatures (for example, less than about 50℃) but only one-phase at higher temperatures (for example, above about 90℃) is disclosed. The compositions comprise a low viscosity base oil which is a hydrocarbon oil and the high viscosity base oil which is a triblock polyalkylene glycol derived from a copolymer of 1, 2-propylene oxide and 1, 2-butylene oxide in which the PO/BO ratio is from 25/75 to 90/10 percent by weight and has a polymerization sequence of PO-BO-PO.
