決定性

Coordination Chemistry of Silica Supported Cr Ions: Types of Cr(II) Ions on Reduced Samplesinds of ions to be diseriminated, so that relative populations, coordinative chemistry and polymerization ability can be established. Species A are definitely the most reactive and comprise the sites active for ethylene polymerization.

使絕緣

Structural Analysis of Supported Chromium Systemsispersion and of the oxidation state of the supported chromium. To achieve this reconciliation it is necessary to review the data in the context of a range of chromium loadings on the support and for a wide range of calcination temperatures.

受辱

Industrial Aspects of Olefin Metathesis/Polymerization Catalystsir Robert Robinson, even called it the most remarkable discovery since Ziegler-Natta polymerization [1]. Actually, in its earliest roots, it can be traced back to the same origins; thus, metathesis is already older than quite a part of this audience.

ALB

串通

Degradation of Polymers by Metathesis Catalysts investigation of copolymers, identification of isomeric structures in subsequently modified polymers, proof of a random distribution of the reaction sites in polymer-analogous reactions, and evidence of reactions at substituents. Application of metathesis degradation is in suitable cases superior to spectroscopic investigation methods.

Consequence

技術

Electrochemical Generation of Catalysts for Alkene Metathesisal by-products and labelling experiments conducted with CD.Cl., it is shown that the metallacarbene initiator arises from a reaction between the transition metal salt and an organoaluminium compound generated in situ by an EC mechanism.
