Abstract:
PROBLEM TO BE SOLVED: To develop an improved PUR dispersion having a high level of hydrolysis stability even when together not using an expensive carbodiimide. SOLUTION: This aqueous dispersion for hydrolysis-resistant coatings contains a polyurethane capable of being obtained by reacting (a) a diisocyanate, (b) a diol, (c) a monomer having at least one isocyanato group or at least one group having reactivity with the isocyanato group, further having at least one hydrophilic or latent hydrophilic group, and thereby enabling the aqueous dispersion of a polyurethane, (d), if necessary, another polyvalent compound having a reactive group, and (e), if necessary, a monovalent compound having a reactive group in the absence of a metal organic catalyst at a temperature of 100 to 180 deg.C for an average reaction time of 1 to 20 hr.
Abstract:
The use is disclosed of hydrophilically modified polyisocyanates in the field of textiles: (i) as cross-linking agents for binders used in pigment dye liquors for dying textiles, (ii) in the form of aqueous dispersions which are substantially free of organic solvents and other emulsifiers, for finishing textiles, or (iii) for the production of textiles with wash-fast lustres.
Abstract:
The invention relates to a method for treating polypropylene textiles, which is characterised in that said textiles are treated with an emulsifier-free aqueous formulation which contains: a) at least one silicon compound having at least one hydrophilic group or b) at least one ethylene copolymer which is obtained by copolymersing ethylene with at least one ethylenically unsaturated mono or dicarboxylic acid or an anhybrid of an ethylenically unsaturated mono or dicarboxylic acid.

Date Nov. 20, 1997The present invention relates to expandable polystyrene beads containing blowing agent which are coated with from 0.01 to 0.5% by weight of a hydrophobicizing agent which melts above 25 DEG C. and has a mean particle size of less than 100 mu m. The beads can be converted into foam moldings having reduced water absorption capacity.
Abstract:
The invention relates to a method for producing non-iron textile materials which contain cellulose by finishing them with an N-methylolether cross-linking agent in the presence of a magnesium chloride cross-linking catalyst. The textile materials to be finished are (a) impregnated with a finishing bath which contains the cross-linking agent in large quantities, are (b) dried to a residual moisture ranging from 3 to 10 wt.%, and are (c) condensed at a temperature ranging from 80 to 145 DEG C.
