Abstract: Water-soluble polymers (I) of esters of acrylic acid (II) and alkyl-polyalkylene glycols (III) are obtained by a method involving azeotropic esterification of (II) and (III) in presence of organic solvent followed by radical polymerisation of the mixture with removal of solvent by azeotropic distillation and replacement of the lost water. Water-soluble polymers (I) of esters of acrylic acid (II) and alkylpolyalkylene glycols (III), obtained by azeotropic esterification of a mixture of (II) and (III) in a mol ratio of (2-3):1 in presence of at least 85 wt% (based on III) of an organic solvent which forms an azeotrope with water, followed by radical polymerisation of the resulting mixture with azeotropic distillation to remove the solvent and with replacement of lost water by recycling or by the addition of fresh water. An Independent claim is also included for a method for the production of (I) as described above.

Abstract: The use of conditioning agents (I) for treating non-metallic surfaces is claimed. (I) comprise polymers consisting of the following monomers :(A) 0.1-100 mol.% vinyl amine; (B) 0-99.9 mol.% other monoethylenically unsaturated monomers ; and (C) 0-5 mol.% monomers with at least two ethylenically unsaturated, non-conjugated double bonds. Also claimed are (i) the surface treatment of non-metallic surfaces by conditioning with these agents; (ii) the preparation of mouldings with metallised surfaces by treating the non-metallic surface of a moulding with one of these agents and then metallising the conditioned surface; and (iii) conditioning baths containing 0.01-5 (0.1-1) wt.% of these agents.

Abstract: A polylactide of the structure I [R -O-CONH]m-R (I> in which R is a polylactide radical having a molecular weight of between 500 and 500,000 or a degree of polymerisation m, based on units of lactic acid, of from about 5 to 5500, and R is the n-valent radical of a tri-, tetra- or polyisocyanate.
