POLYFUNCTIONAL SILOXANE OLIGOMERS OF ASYMMETRIC STRUCTURE AND METHOD FOR THEIR PREPARING

摘要

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. ^ 24 cl, 8 ex
