Fluoroalkyloxylakyl containing organopolysiloxanes

摘要

This invention relates to fluoroalkyloxyalkyl diorganopolysiloxanes having the general formula <IMAGE> where R1 represents fluoroalkyloxyalkyl groups of the general formula -(CH2)a-O-CbR2bH in which the hydrogen atom is in the beta position to the ether oxygen, a is 2, 3 or 4; b is an integer having a value of from 1 to 6; R2 represents an alkyl group having from 1 to 8 carbon atoms whose terminal units may also contain an amino or a thiol group, or an alkenyl group having 2 or 3 carbon atoms, or an aryl group having from 6 to 8 carbon atoms or hydrogen; R3 represents the group having the formula -(CH2)c-CdF(2d-e+l)Hale , in which Hal represents a terminal chlorine, bromine or iodine atom, c is 2, 3 or 4; d is an integer having a value of from 1 to 18; e is 0 or 1; R4, R5 and R6 are the same as R2; X and Y are the same or different and represent condensable terminal groups or trialkylsiloxy groups in which the alkyl groups have from 1 to 6 carbon atoms; m has a value of from 0.05 to 0.9; n has a value of from 0 to 0.6; and p has a value of from 0.1 to 0.8 with the proviso that the sum of m+n+p=1.
