Abstract: Polymeric condensation prods. (I) contg. repeating units of formula (II) are useful as conditioning agents for the pretreatment of non-metallic surfaces (''pre-dip'') before activation for subsequent chemical metallisation. In the formulae A1 A2 = 2-4C alkylene; A3 = opt. OH-substd. 2-4C alkylene; R1, R4 = H, 1-12C alkyl or benzyl; R2, R3 = 1-12C alkyl or benzyl; R5, R6 = 1-12C alkyl, OH-substd. 2-12C alkyl or benzyl; n,m,o,p,q,r = 0 or 1. Repeating units have formula (III) (with R7, R8 = 1-12C alkyl or benzyl; s, t = 0 or 1); (I) is a condensation prod. derived from piperazine and epichlorhydrin, in which the N atoms are 0-100% quaternised with 1-12C alkyl gps. or 0-80% quaternised with benzyl gps., and is used in the form of a salt soluble in the aq. application bath; concn. of (I) is 0.001-1 wt.%, bath temp. is 10-60 deg.C and application time is 15 secs. 30 mins.

Abstract: The use of polyalkyleneimines, having 2 to 4 carbon atoms in the alkylene groups, and/or of their quaternary salts, which polyalkyleneimines are soluble in the aqueous bath in which they are employed and whose nitrogen atoms are quaternized to an extent of up to 80 % with C1 to C8-alkyl groups, as conditioning agents for the pretreatment of nonmetallic surfaces before they are primed (given a nucleating treatment) for a subsequent chemical metallization. This is a cost-effective method of obtaining uniform and well-adhering metal coatings.

Abstract: The new 1-monochloro- and 1,1-dichloro-prop-2,3-ene-3-sulfonic acids and their metal salts, and a process for their manufacture by reacting chloropropanesulfonic acid compounds with alkali metal carbonates, alkali metal bicarbonates and/or alkaline earth metal hydroxides at from 5 DEG to 100 DEG C to give 1-chloro-prop-2,3-ene-3-sulfonates which may then be reacted with acid compounds in a second step.
