UHMWPE/HDPE in-reactor blends, prepared by in situ polymerization: Synthetic aspects and characterization

This work covers the synthesis and characterization of in-reactor Ultra-High Molecular Weight Polyethylene/ High Density Polyethylene, UHMWPE/HDPE, blends by in situ polymerization in a single reactor, through dual catalyst immobilization. These blends are synthesized combining two different catalys...
