each W is independently selected from the group consisting of H, F, Cl, Br, I, and (CY2)mCY3, provided that at least one W in the compound according to formula (Ia) is (CY2)mCY3;
each Y is independently selected from the group consisting of F, Cl, Br, and I;
each Z is independently selected from the group consisting of H, OH, (CW2)pCW3, CY3, OCW3, O(CW2)pCW3, OCW((CY2)mCY3)CWCW2, (CW2)pOH, polyalkylene glycol (“PAG”), and polyester;
n is an integer from 2 to 49;
m is an integer from 0 to 3;
p is an integer from 0 to 9;
the weight average molecular weight (Mw) is ≤5500; and
the polydispersity index is ≤1.45; and
wherein the heat transfer portion comprises one or more heat transfer compounds selected from the group consisting of (hydro)fluoroolefins (HFOs), hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), perfluoroalkyl iodides, and hydrocarbons.
