Abstract (en)

[origin: WO9815540A1] The invention relates to Xn(alkoxy)(6-n)alkyl melamine, in which X = halide, n = 1-6, and the alkoxy group and the alkyl group contain 1 to 6 carbon atoms, a process for the preparation of these compounds and the use of these compounds as initiator in a cationic polymerization of monomers to form a polymer. The invention also relates to the polymer obtained with this initiator and to the use of the resulting polymer as impact modifier in melamine, phenol or urea containing resins.
