Abstract: The parent patent concerns copolyamides (I) with K values of 35-70 (1% soln. in 96% H2SO4 at 20 degrees C), obtd. by melt condensn. at 180-300 degrees C from 5-18 (wt.)% hexamethylenediamine adipate (II) and 95-82% salt (III) of piperazine and mixts. of decane-1,10-dicarboxylic acid and azelaic acid in 70:30 to 95:5 molar ratio, opt. in the presence of traces of a monocarboxylic acid as mol. wt regulator. In this patent of addn. the novel feature is that a salt (IV) of adipic acid with a 5-20, pref. 6-15C (cyclo)aliphatic prim. diamine is used instead of (II). (I) are specified for dressing artificial leather with a plasticised PVC surface. (I) form stable solns. in the usual solvent mixts., adhere firmly and permanently to the surface, have good feel, gloss and mechanical properties and retard plasticiser and dyestuff migration.

Abstract: Easily crosslinkable copolymers are prepd. by the aq. emulsion copolymerisation of, by wt. w.r.t. total monomers, (a) 45-97% mono-olefinically unsatd. carboxylic acid esters, the homopolymers of which have vitreous transition temp. below 15 degrees C., (b) 1-15% mono-olefinically unsatd. aldehydes, (2) 2-30% hydroxyalkyl esters of 3-4C alpha, beta-mono-olefinically unsatd. monocarboxylic acids, (d) 0-50% styrene, acrylonitrile and/or mono-olefinically unsatd. carboxylic acid esters, the homopolymers of which have vitreous transition temps. >15 degrees C. and (e) 0-10% alpha, beta-mono-olefinically unsatd. 3-5C carboxylic acids and/or their amides. Molar ratio (b):(c) is 1:0.5 to 1:3. Pptd. opt. filled rubber-elastic polymers can be used as sealing compsns. and as heat- and hot oil-resistant hoses. The aq. dispersions are used for finishing leather, as binders for fleeces, in textile printing, paper sizing and textile coating.

Abstract: A specific copolyamide and its use for finishing leather and leather substitutes, particularly those of polyurethane. A particular advantage of the copolyamide is its sealing effect counteracting the migration of dyes, plasticizers and fats, combined with other advantages such as good mechanical properties and the stability of the solutions.

According to DT 28 00 149, (I) is used for dressing artificial leather with a plasticised PVC surface. Improvement is that (I) is used for dressing leather or artificial leather with a polyurethane surface. (I) forms stable solns. in the usual solvent mixts., adheres firmly and permanently to the surface, has good feel, gloss and mechanical properties and retards plasticiser and dyestuff migration.
