METHOD OF PRODUCING POLYMER PRODUCTS CONTAINING UNSUBSTITUTED CYCLOPROPANE GROUPS IN MACROMOLECULES Russian patent published in 2015 - IPC C08C19/06 C08F8/08 C08L15/00

Abstract RU 2571431 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing polymer products with unsubstituted cyclopropane groups of general formula (1) , where (a+b):(c+d)=60-95:5-40 mol %. The method includes reacting atactic-structure 1,2-polybutadiene with a diazo-compound in a medium of methylene chloride in the presence of a metal complex catalyst at 0-5°C. The molar ratio 1,2-polybutadiene:diazomethane:catalyst is equal to 1:0.5-2.0:0.01. As the catalyst copper (II) triflate - Cu(OTf)₂ or a copper (I) triflate and benzene complex - (CuOTf)·0,5C₆H₆are used.

EFFECT: obtaining polymer products containing in macromolecules unsubstituted cyclopropane groups, having a different degree of functionalisation and different molecular weight, which can be intentionally altered in a wide range of values.
