METHOD OF PRODUCING POLYMERS CONTAINING CYCLOPROPANE GROUPS Russian patent published in 2012 - IPC C07C61/04 C08F8/02 

Abstract RU 2447055 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing polymers with substituted cyclopropane groups in the backbone chain or side chains of general formula (1): . The method involves reaction of 1,2-polybutadiene with alkyldiazoacetate in the medium of an organic solvent in the presence of a catalyst. The catalyst used is copper (II) triflate - Cu(OTf)2, with molar ratio 1,2-polybutadiene: alkyldiazoacetate: catalyst equal to 1:0.5-1:0.01.

EFFECT: obtaining polymer products (1) with higher degree of functionalisation (conversion of unsaturated links to cyclopropane groups), with different molecular weight, which can be intentionally varied in a wide range of values.
