Abstract: The invention concerns a process for preparing fine-particle mixtures comprising between 97 and 10 wt % of at least one amphiphilic polymer whose softening temperature is above 35 DEG C, and between 3 and 90 wt % of at least one inorganic solid having a particle size of up to at most 500 mu m. According to this process the two components are heated to a temperature which is above the softening temperature of the polymer. The two components are then mixed, broken down in the molten state and rapidly cooled, to a temperature at which practically no separation occurs. The particles are optionally broken down further at temperatures of less than 50 DEG C such that the particle size is between 50 mu m and 5 mm. The invention further concerns the use of these mixtures as detergent additives.

Abstract: Resin mixts. (I) contain (A) 100 pts.wt. polyfunctional epoxy cpd(s)., (B) 2-206 pts.wt. N-contg. hardener, (C) 3-30 pts.wt. thermoplastic or rubber which is soluble in (A), and (D) 0.3-10 pts.wt. finely divided silica. Pref., (B) is an aromatic diamine or dicyandiamide and thermoplastic (C) is a polyether-sulphone; (D) has specific surface (BET) 50-500 m2/g and particle size 5-50 nm, and is pref. hydrophilic silica. Pref., (A) are diglycidyl ethers of Bisphenol A, Bisphenol F or dicyclopentadienylphenol (e.g., DER 332, Epikote 828, Araldite PY 306, Tactix 556, etc. (RTM)), Araldite MY 721 (RTM: tetraglycidyldiaminodiphenylmethane), triglycidyl-p-amino-phenol or triglycidyltriphenylmethane). (B) is, e.g., 4,4'-diamino-diphenylsulphone (DDS) or dicyandiamide, (C) is polyether-sulphone, (D) is Cab-O-Sil M5 or Aerosil 200 (RTM). USE/ADVANTAGE - Epoxy resin mixts. are used for the prodn. of prepregs for fibre-reinforced composites. Mixts. have improved rheological properties, i.e., relatively constant high viscosity under curing conditions (so that the resin does not run out) combined with a sufficiently low viscosity for the impregnation stage.

Abstract: In the process, a mixture of bismaleimide and aminophenol is heated in the presence of an amine as addition catalyst and in the presence of an inhibitor, vinyl or allyl monomers and, if desired, epoxy resins and peroxide initiators are added, and the mixture, as a melt, is applied to reinforcing fibres. The prepregs and semifinished products can be cured to form composite materials for the automotive and aerospace industries.
