Abstract: Prepn. of water-resistant foils and coatings from water-soluble or water-dispersible grafted proteins comprises tempering at over 40 deg.C and/or treating with a protein-hardening agent. The proteins are obtd. by radical-initiated polymerisation of monoethylenic unsatd. monomers in the presence of proteins where the wt. ratio of monomer to protein is 0.5-90:99.5-10. Diapers, with the above foil or coating on the outer side, are also claimed. USE/ADVANTAGE - The foils/coatings are esp. useful for disposable diapers. They are suitable for composting and dissolve relatively quickly in the alkaline pH-regege

Abstract: Use of certain quaternary salts of di- and/or trialkanolamines, which salts are soluble in an aqueous application bath, as conditioners for the pretreatment of nonmetallic surfaces of mouldings before the nucleation thereof for a subsequent chemical metallisation. … This gives outstandingly uniform and firmly adhering metal coatings.

Abstract: New polyacetals (A) are prepd. by reacting (a) a dialdehyde OHC-(-A-)n-CHO (I) with (b) a polyol carboxylic acid (II) contg. 5-7C and at least 3 OH gps., with mole ratio 1:0.25-4, in aq. medium and in presence of acid catalyst. A = (CH2)m, -CH2-C(Me)H-CH2- or 1,4-phenylene; m = 1-4; n = 0 or 1. Pref. reaction is at up to 140 deg.C and water is removed from the mixt. during reaction.

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.
