Examples of 'ziegler-natta catalysts' in a sentence
Meaning of "ziegler-natta catalysts"
Ziegler-Natta catalysts are a class of catalysts used in polymerization reactions, specifically in the production of polyolefins like polyethylene and polypropylene. These catalysts are named after the chemists Karl Ziegler and Giulio Natta, who pioneered their development. Ziegler-Natta catalysts are highly efficient in promoting polymerization reactions and are widely employed in the plastics industry for the synthesis of various types of polyolefins
