Synthesis of oxazoline functionalized polypropene using metallocene catalysts

Using two different zirconocene/MAO catalyst systems, propene was copolymer ized with the comonomers 2-(9-decene-1-yl)-1,3-oxazoline and 2-(4-(10- unde cene-1-oxo)phenyl)-1,3-oxazoline, respectively. The catalysts used were rac -Et[Ind](2)ZrCl2 and rac-Me2Si[2-Me-4, 5-BenzInd](2)ZrCl2. Up to 0.53 mol-% oxazoline could be incorporated into polypropene. Oxazoline content, molec ular weight, degree of isotacticity and melting behavior were dependent on the catalyst system, comonomer structure and comonomer concentration in the feed.
