The titanium compound may be either a titanyl compound of the formula X m TiOY o or a titanium salt of the formula X m TiY o , 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 C a H b O c , 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.
