ABSTRACT A method of making grafted polyalphaolefin polymer comprising providing (a) an aluminum compound having the formula R3Al2X3 or RnAlX3-n, wherein R is C1-C18 alkyl, C7-C9 aralkyl, C7-C9 alkaryl or C6-C10 aryl; X is Cl, Br or I, and n is an integer from 1 to 3; (b) a polyhalogenated compound having the formula (-CH2CR1R2)myp, wherein R1 is hydrogen or C1-C3 alkyl; R2 is linear or branched C2-C30 alkyl; Y is Cl, Br or I; m is an integer from 3 to 3000; and p is an integer of at least 3; and (c) a cation- ically polymerizable monomer having the formula CH2=CR1R2, wherein R1 and R2 have the meanings above; and (B) bringing into contact above (a), (b) and (c) under polymerization conditions. The compositions made by the disclosed process are useful as lubricating oils and hydraulic fluids.
