Abstract:
A compound containing at least two functional groups with at least one polyalkyleneglycol substituent and at least two halogen substituents, the compound having a number average molecular weight of 200 to 10,000 and being represented by the formula (X)a(R)b(R1)cSiâ€”C(R4)(R5)â€”Si(X)d(R)e(R2)f, in which:X is a halogen atom selected from the group consisting of F, Cl, Br and I; R1 and R2 are the same or different and independently represent hydrogen, an alkyl group containing 1 to 10 carbon atoms, or a C1 to C10 alkyl group having F or Cl substituents; R4 and R5 are the same or different and independently represent hydrogen, Si(X)a(R)b(R1)c or Si(X)d(R)e(R2)f; R is a polyalkyleneglycol group represented by the formula {C(R6)(R7)CH(R8)C(R6)(R7)Z}â€”{C(R6)(R7)C(R6)(R7)O}gR9; R6, R7 and R8 are the same or different and independently represent hydrogen, an alkyl group containing 1 to 10 carbon atoms, or a C1 to C10 alkyl group having F or Cl substituents; R9 is methyl or ethyl; Z is oxygen or p-substituted benzene ring (C6H4); a and d are the same or different and independently represent a number from 1 to 3; b and e are the same or different and independently represent a number from 0 to 2; c and fare the same or different and independently represent a number 0 or 1, wherein a+b+c+d+e+f=6; and g is a number from 1 to 20.
