摘要

"Polu00ecmero additive to a medium of alkaline bath of electroplating of zinc or zinc alloy bath, means of alkaline zinc or zinc alloy.Process for eletrogalvanizar zinc and / or zinc alloys on a conductive substrate, and the use of polu00ecmero ".An additive polymer means and processes for electroplating zinc and zinc alloy alkali comprises the reaction product of one or both of (I) a first di tertiary amine of formula(1) in which R represents and is 2 to 6, R reepresenta ch or CH ~ 2 ~ 3 ~ ~ H ~ 5 ~ and each R may be the same or different, and M is 2 to 4.And a second Di tertiary amine of the formula (2), in which B is C ~ g ~ H ~ 2 ~ + 1 and g = 0 or an integer, the groups B being the same or different, and F = 0 or an integer.And R '' represents ch or CH ~ 2 ~ 3 ~ ~ H ~ 5 ~ and each R 'may be the same or different, with (II) a di - Halo c16-18-alkane formula 4):, where represents a halogen atom, and N is at least 2.The resulting polymer preferably having the general structure (1) where 0 242 x 242 1.0 242 y - 1 and (x or y) or (x and y) = 1, Z is at least 2 and when y = 0, n is at least 3.
