POLYSILOXANE COMPOUND WITH FIVE-MEMBERED CYCLIC CARBONATE AND METHOD OF OBTAINING THEREOF Russian patent published in 2014 - IPC C08G77/38 C08G77/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel polysiloxane compound with five-membered cyclic carbonate and a method of its obtaining. Claimed is the polysiloxane compound with five-membered cyclic carbonate of formula (1), where A stands for or , where R₁ stands for an alkylene group, containing from 1 to 12 carbon atoms and can be bound through an element O and/or -(C₂H₄O)_b-, R₂ stands for the direct bond or an alkylene group, containing from 2 to 20 carbon atoms, and, when R₂ stands for the direct bond, carbon of an alkylene group R₁ or carbon of a group -(C₂H₄O)_b- is bound directly with Si, bound with R₂ in formula (1), b stands for a number from 1 to 300, a stands for a number from 8.2 to 9.2. Also claimed is the method of obtaining the claimed compound.

EFFECT: claimed compound makes it possible to obtain polyhydroxypolyurethane resins with improved exploitation characteristics.
