Cross linkable mass, obtained by condensation reaction using organosilicon compounds (II)containing units and physical propellants, useful e.g. to prepare molded article and for the insulation of electric or electronic devices

摘要

Cross linkable mass (I), obtained by the condensation reaction using organosilicon compounds containing silicon units (a1); and physical propellants, is claimed. Cross linkable mass (I), obtained by the condensation reaction using: organosilicon compounds containing units of formula ([A-CR1>R1>]cSiR1aY1bO(4-a-b-c)/2) (a1); and physical propellants, is claimed, where the organosilicon compound exhibits at least one unit with c different from 0 and at least three residues of Y1>. A : organic residue having N, O, S, P or carbonyl, preferably R3>R4>N (connected through a ring), R5>O-, R6>S-, (R7>O)2P(=O)- or O=C=N-; R : monovalent optionally substituted hydrocarbon; R1>H or monovalent optionally substituted hydrocarbons; Y1>hydrolyzable group; R3>, R4>R1>; R5>CH3(CH=CH2)-(C=O)- or CH3-O-(C=O)-; R6>, R7>R1>; either a, b : 0-3; and c : 0-2; or a+b+c : = 4.
