An Absolute Test of Rival Theories for MWDs in Heterogeneous Polymerization-MWDs during Quasi-Livingval theories are invalid. To understand this situation, a new theory of non-uniform sites not only with propagation but also slightly with transfer rate is proposed. The non-uniformity that conforms to a popular kinetic model gives a unified explanation about the abnormal decay kinetics recognized i字谜游戏 发表于 2025-3-28 22:27:27
Kinetics and Mechanism of Ethylene Polymerization and Copolymerization Reactions with Heterogeneousin the literature yet: (a) formation of deuterated ethylenes in ethylene homopolymerization reactions in the presence of deuterium, and (b) an apparently increased reactivity of α-olefins in chain initiation reactions involving the Ti-H bond. Both effects were confirmed experi-mentally.Abduct 发表于 2025-3-29 02:06:21

A DFT quantum-chemical study of the structures and reactive sites of polymethylalumoxanea Al-O dative bond and the formation of acidic tricoordinated Al-atoms and basic dicoordinated O-atoms in the MAO molecule. Two molecules of AlMe. are associated with these sites. The total heat of the TMA interaction with MAO depends on the n value and the MAO structure. The reactive sites of MAO are proposed based on the obtained data.Inflamed 发表于 2025-3-29 11:24:32
Conference proceedings 1999e compounds have not lost their fascination. The birthday of Karl Ziegler, the great pioneer in this metalorganic catalysis, is now 100 years ago. Polyolefins and polydienes produced by Ziegler-Natta catalysis are the most important plastics and elastomers. New impulses for the polymerization of oleMIME 发表于 2025-3-29 17:53:58

New insight into propene polymerization promoted by heterogeneous Ziegler-Natta catalystsophisticated models of chain propagation applicable for the first time in a statistically significant manner. In this presentation, the most recent applications to «high-yield» MgCl.-supported Ziegler-Natta catalysts are illustratedHAWK 发表于 2025-3-30 04:13:31
