Hydridoboranes as modifiers for single-site organochromium catalysts: from low- to ultrahigh-molecular-weight polyethylene

Going to great lengths: The use of hydridoboranes as new modifiers for chromium-catalyzed olefin polymerization allows the preparation of polyethylene with a precisely tunable ultrahigh molecular weight. This effect can be understood by a reversible protection of the active catalyst by the borane (s...

Description
Summary:Going to great lengths: The use of hydridoboranes as new modifiers for chromium-catalyzed olefin polymerization allows the preparation of polyethylene with a precisely tunable ultrahigh molecular weight. This effect can be understood by a reversible protection of the active catalyst by the borane (see scheme).
