3251 PROCESS FOR PRODUCING STARCH/POLYOLEFIN POLYMER COMPOSITIONS ABSTRACT OF THE DISCLOSURE A process is disclosed for producing starch/ polyolefin polymer compositions by polymerization of at least one olefin in the presence of a Ziegler-Natta catalyst. The Ziegler-Natta catalyst used is obtained by contacting dried starch with an aluminum trialkyl followed by intro- ducing a transition metal compound of the formula (cyclopentadienyl)n MRm wherein M is selected from the group consisting of Cr, Ti, V or Zr, R is a lower hydrocarbon radical or acetyl acetonate, and n and m are integers from 0 to 4 and n + m equals 2 to 4.
