POLYFUNCTIONAL SILOXANE OLIGOMERS OF ASYMMETRIC STRUCTURE AND METHOD FOR THEIR PREPARING Russian patent published in 2005 - IPC

Abstract RU 2266908 C1

FIELD: organic chemistry, chemistry of polymers.

SUBSTANCE: invention describes new polyfunctional siloxane oligomers of asymmetric structure of the general formula (I): (C₂H₅O)₃SiO[Si(CH₃)₂O]_nSi(CH₃)₂A wherein A means hydrogen atom (H) or the following radicals: -CH₂Cl; -CH=CH₂; -H₂OC(O)C(CH₃)=CH₂; -(CH₂)₃OC(O)C(CH₃)=CH₂; -(CH₂)₃OCH₂CH(O)CH₂; n = 0 or 3, and a method for their preparing. Invention provides preparing new compounds comprising asymmetric molecules that can be used as the parent compounds in preparing polyfunctional organosiloxanes of three-dimensional polycyclic structures.

EFFECT: improved preparing method.
