Methylaluminoxane: synthesis, characterization and catalysis of ethylene polymerization

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

Three types of methylaluminoxanes (MAO-1, 2 and 3) were synthesized with different average molecular weights. In each MAO synthesis, two types of MAOs were isolated (Fractions A and B). Fractions A and B differ by the presence of different methyl/aluminum molar ratio and mol% trimethylaluminum. Kinetics of ethylene polymerization were studied using both fractions A and B of MAOs 1,2 and 3 as cocatalysts and Cp2ZrCl2 as catalyst at atmospheric pressure of ethylene. The poly(ethylene)s were analyzed for their molecular weight.

The data from published literature, especially originating from different laboratories, is difficult to compare because of the nonavailability of complete properties of MAO used upon which the whole catalysis is dependent. Only in a very few instances is complete characterization of MAO including the TMA content explicitly indicated in publishedpapers or patents.
