MIXED METAL CATALYST SYSTEMS WITH SPECIFICALLY ADAPTED HYDROGEN RESPONSE Russian patent published in 2015 - IPC C08F10/00 C08F4/76 

FIELD: chemistry.

SUBSTANCE: described is a polymerisation catalyst system and a polymerisation method using said catalyst systems. The polymerisation catalyst systems may include a) a first catalytically active compound and b) a second catalytically active compound, the first catalytically active compound including an oxadiazole-containing compound. The oxadiazole-containing compound corresponds to the structural formula given below, wherein M is selected from a group comprising Ti, Zr and Hf; values or radicals from R² to R¹⁰ are given in the claim

;

X is at least one leaving group.

EFFECT: oxadiazole-containing compound substantially has no hydrogen response, which enables improved and/or specific regulation of properties of the product when producing polymers using the described catalyst system.
