    Abstract: Preparation of copolymers which are clear in water from A) 45 to 90% by weight of N-vinylpyrrolidone, B) 10 to 55% by weight of a vinyl ester and C) 0 to 10% by weight of further copolymerisable monomers by free radical polymerisation in an organic solvent in the presence of a free radical initiator and separation of the organic solvent and other volatile components by distillation, by carrying out the polymerisation until the N-vinylpyrrolidone content of the reaction mixture corresponds to 5 to 1% by weight of the amount of N-vinylpyrrolidone used, substantially separating off the organic solvent and other volatile components by distillation, adding water to the mixture, leaving the aqueous solution for 1 to 10 hours at 50 to 100 DEG C with further addition of free radical initiators and then virtually completely removing volatile organic components by steam distillation.

The novelty is that 0.5-30 % of the quantity of alkali metal cyanide required for reaction is added to the glycine derivs. or their precursors and then the remaining amt. of alkali metal cyanide and the formaldehyde is added simultaneously over 0.5-12 hrs.

    Abstract: The use of bis-(dicarboxylic acid) diaminoalkylene derivatives of formula (I) as complex-forming agents in textile dyeing and pre- or post-treatment is claimed. In (I), R , R = H, 1-8C alkyl, 2-8C alkenyl, phenyl, benzyl, or 1-4C hydroxyalkyl or hydroxy-halo-alkyl; M = H, alkali metal, ammonium or substituted ammonium; l, m, n = 0-6; A1 = 2-3C alkylene, optionally substituted on one, two or all C atoms with one or two hydroxy, 1-6C alkyl, 2-6C alkenyl, 3-6C cycloalkyl, or 3-8C cycloalkenyl, aryl, alkylaryl, heteroaryl or alkyl-heteroaryl groups. Also claimed are: (i) a process for the pretreatment, post-treatment or dyeing of textiles or textile precursors in the manufacture or processing of textiles, in which the material is subjected to a treatment bath containing 0.01-20 (preferably 0.1-10, more preferably 0.5-3) g/l (I), and (ii) baths used for this process containing (I) in the above amounts.

    Abstract: Hydroxyalkylaminocarboxylic acid derivatives of formula (I) R -CH(OH)-CH(R )-N(R )-Y-COOM (I) are used as dispersing agent in dyestuffs or in preparations containing UV absorbers or optical brighteners.

Also claimed is use of (I) in dye baths for dyeing with dispersion dyes using the exhaustion process, in dye baths for dyeing with vat dyes and in textile treatment liquors containing UV absorbers or optical brighteners.
