Patent ID: 6987157

Claim:
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 2 CH 2 — 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 2, or amine group, or whenever -Z- is —CH═CH— R1 and R2 are independently H, halogen, NO 2, an amine group, 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 2, or amine group, and 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 2 , or amine group, or R3 is a nullity; R4 is —CH(R5)—CH 2 —, —CH 2 —CH(R5)— or a combination of these; 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 2 CH 2 —, R1 and R2 are free of halogen and nitrogen, and all R5 groups are solely some combination of H and methyl, then —CH 2 CH 2 — groups must make up on average at least 60 percent by weight of the total R4 groups per molecule; m=3 to 100 with the proviso that the range form is expanded to 1 to 100 whenever -Z- is —CH 2 CH 2 — and the equivalent polydispersity of R is less than 1.4 or whenever R contains halogen, NO 2 , an amine group, or is aldehyde, keto or ester functional; R6 is H, an alkyl group or and R7 an alkyl group, 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.
