摘要： Functional polymers containing hydroxyl groups as supports for use with catalysts can increase the activity of these catalysts which results in improved ethylene polymerization. The present invention seeks to provide catalysts with improved activity by incorporating 2-hydroxyethyl methacrylate (HEMA) into the support of the catalyst.
