Abstract: Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrofluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.

Abstract: A catalyst composition for preparing polyesters comprises a titanium compound and one or more catalyst enhancers. The titanium compound may be either a titanyl compound of the formula XmTiOYo or a titanium salt of the formula XmTiYo, where each X is independently selected from the group consisting of H, Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba and ammonium; m=0, 1 or 2; Y is a ligand of the formula CaHbOc, wherein a=1 to 30, b=0 to 60, and c=1 to 10; and o=2, 3, or 4. The catalyst enhancer may be selected from either or both of two classes: 1) compounds selected from the group consisting of oxalate and C1-C26 carboxylate salts of Li, Na, K, Rb, Cs, Be, Ca, Mg, Sr, and Ba; and 2) compounds selected from the group consisting of soluble compounds of Al, Co, Zn, and Sn.
