Abstract: A graft copolymer A is constituted by (A1) 1 to 90 % by weight, with respect to A, of a particulate graft copolymer A1 having a glass transition temperature below 0 DEG C and an average particle size below 40 nm; and (A2) 10 to 99 % by weight, with respect to A, of a graft coating A2 made of olefinically unsaturated monomers that form soft or hard polymers. The average particle size of the graft copolymer A as a whole is lower than 50 nm. Also disclosed is a moulding material containing this graft copolymer.

Abstract: Emulsifier-free aqueous polyurethane dispersions are prepared by reacting (a) dihydroxy compounds, (b) diisocyanates and (c) chain extenders to give a prepolymer having terminal isocyanate groups, then reacting the prepolymer with (d) salts of aliphatic aminocarboxylic or -sulfonic acids or amino-containing or hydroxyl-containing tertiary ammonium salts, dispersing the resulting polyurethane in water and, if required, removing the organic solvent by distillation. In the process, an organic condensation resin which is dissolved in a solvent is admixed before the polyurethane obtained is dispersed in water.

Abstract: New star-shaped polyenes are of formula (I): A = 6-30C aromatic ring system or heteroaromatic ring system contg. N, O or S as hetero-atom; R1-3 = polyenes with 2-50 double bonds. New polymeric star-shaped polyenes (II) obtd. by crosslinking some (I), and the prepn. (I) and (II) are also claimed. USE/ADVANTAGE - (I) and (II) are used as electroconductive materials (claimed). (I) are soluble and their substits. can have definite orientation, making them of particular interest in the optical and optoelectronics fields. They are suitable for incorporation in high mol. systems with definite structure.
