## Abstract The rheology of linear and branched metallocene polyethylenes (mβPEs) was investigated. The linear metallocenes were prepared by gasβphase polymerization, while the branched PEs were commercial resins. Molecular parameters such as __M__~__w__~, branch type, and molecular weight distribu
## Abstract The crystallization and morphology of some metallocene polyethylenes with wellβcontrolled molecular weight and branching content were investigated by DSC, WAXD, PLM and SALS. The banded spherulites observed in linear PE are not seen in crystallization of branched PEs. The small spheruli
