New organosilicon compounds comprising a multifunctional polyorganosiloxane bearing at least one ethylenic double bond activated imido type and preparation procedures.

摘要

Process for preparing organosilicon compounds comprising essentially linear multifunctional polyorganosiloxanes having the following mean formula: (See formula) in which: (1 ') the symbols T1 are chosen from the radicals HO1 / 2 and R1O1 / 2, in which the radical R1 represents an alkyl, linear or branched radical having from 1 to 5 carbon atoms; (2 '') T2 symbols, identical or different from the symbols T1, are chosen from HO1 / 2 and R1 O1 / 2 moieties and the rest (R2) 3SiO1 / 2, in which the radical R1 is as is defined above in point (1 '') and in which R2, identical or different, radicals each represent a monovalent hydrocarbon group chosen from an alkyl radical, linear or branched, having from 1 to 6 carbon atoms; a cycloalkyl radical having from 5 to 8 carbon atoms, and a phenyl radical; (3 '') the symbols R2 are as defined above are in (2 ''); the symbols X are identical or different, each represent a function bearing a activated double ethylene bond, chosen from the radicals having the formulas (II / 1), (II / 2), (II / 3) below, and mixtures: (See formulas) * with conditions ...
