Abstract:
1. A silicone based polyether comprising a monovalent group, R, with R having an average formula: wherein, Z is bonded to Si and -Z- is —CH 2 CH 2 — or —CH═CH—; whenever -Z- is —CH R1 and R2 are independently alkyl, phenyl, an alkyl substituted phenyl, a phenyl substituted alkyl, or one of the four latter groups substituted by one or more of halogen, NO whenever -Z- is —CH═CH— R1 and R2 are independently H, halogen, NO regardless of choice of -Z- R1 and R2 may be independently aldehyde, keto or ester functional; R3 is a divalent hydrocarbon group which may be substituted by one or more of halogen, NO R4 is —CH(R5)—CH R5 is H, methyl, ethyl, phenyl or may vary among these within the same molecule in any proportion or order; with the proviso that when -Z- is —CH whereby the equivalent polydispersity of R is less than 1.6, and wherein at least one of R1, R2 and R3 is chlorine, bromine, chlorine substituted, or bromine substituted.
