THE STOPPED-FLOW TECHNIQUE FOR 1-ALKENE POLYMERIZATION

Popis výsledku v původním jazyce

The stopped-flow polymerization technique enables to study early stages of a-olefin polymerization on Ziegler-Natta or metallocene catalysts. This technique allows performing the polymerization experiments shorter than average lifetime of the growing polymer chains (ca. 0.2 s). Thus the stopped-flow technique is considered as one of the most powerful tool for the investigation of the catalyst active sites performance and elucidation of the olefin polymerization mechanism based on the analysis of obtained polymer material. In this work the stopped-flow technique is further utilized for the development and preparation of new polymer materials based on the preparation of special block copolymers as polypropen-block-poly(propen-co-ethen). For this purpose,the new experimental facility suitable for the preparation of relatively high amount of the copolymer materials was constructed. The facility is designed for the copolymer synthesis close to the conditions applied in industry (polymeriza
