Heterocarboxylates of dichlorobis(cyclopentadienyl)zirconium(IV) and dichlorobis(cyclopentadienyl)titanium(IV)

Reactions of Titanocene Derivatives with Molecular Carboxylic Acids and Copolymers Bearing Carboxylic Acid Groups

“…[20][21][22][23][24][25] These results suggest that it may be possible to prepare soluble titaniumcontaining copolymers by reacting these titanocenes with copolymers bearing carboxylic acid residues if the first X group is replaced at a significantly higher rate than is the second. Two copolymers that contain carboxylic acid residues and have mechanical properties much like those of polystyrene are poly(styrene-co-methacrylic acid) and poly[styrene-co-(4-carboxystyrene)].…”

“…This decomposition does not appear to involve the formation of bis(carboxylato)titanocenes. We have prepared an authentic sample of the bis(benzoato)titanocene [3] REACTIONS OF TITANOCENES WITH CARBOXYLIC ACID GROUPSfrom dichlorotitanocene and benzoic acid 25 24 The instabilities of the carboxylato(phenyl)titanocenes do not appear to be due to the solvent, as similar results were obtained when the reactions were carried out in tetrahydrofuran-d g . Because the processing of mandrels requires that the polymers be stable at elevated temperatures, no studies of the reactions of diphenyltitanocene and poly(styrene-comethacrylic acid) copolymers were carried out.…”
