Abstract: The invention concerns agglomerated particles of finely divided polymers which are water-soluble or capable of swelling in water and contain ammonium carboxlyate groups, and a process for their preparation by azeotropic dehydration of water-in-oil emulsions of the polymers, which are water-soluble or capable of swelling in water and contain ammonium carboxylate groups, in the presence of 0.1 to 40 wt %, relative to the polymers, of polyalkylene glycols, which have an agglomerating effect and are obtained by the addition of C2 to C4 alkylene oxides to alcohols, phenols, amines or carboxylic acids and which contain at least two alkylene oxide units incorporated by polymerization, and additionally from 0.1 to 20 wt %, relative to the polymers, of protective colloids which are obtained by radical copolymerization of C8 to C40 mono-olefins with monoethylenically unsaturated C4 to C6 dicarboxylic acid anhydrides in the manner of a substance polymerization at temperatures from 80 to 300 DEG C to form copolymers having molar masses of 500 to 20,000 g/mol. The invention further concerns the use of the agglomerated polymer particles as thickeners for textile pigment printing inks.

Abstract: A process for the preparation of reinforced rubber vulcanisates by vulcanisation of mixtures of natural rubber or synthetic rubbers with novolak resins in the presence of a curing agent, in particular hexamethylenetetramine, where the temperature at which the resins are mixed in is kept at or up to 50 DEG C below the softening points of the resins.

Abstract: Essentially phenol-free phenol resol ethers which are bonded via o,o'-methylene ether groups are prepared by a process in which A. where the process is carried out beginning with the methylolation in an aqueous medium, the methylolation is carried out in the presence of 0.5-10% by weight, based on the phenol employed, of Me++ ions, the latter are then removed as a sparingly soluble salt, the water present as a solvent in the reaction mixture is removed at 30 DEG -80 DEG C. in the presence or absence of one or more monohydric, dihydric or trihydric alcohols and an entraining agent, and the water of reaction formed during the etherification is separated off at 45 DEG -120 DEG C., and B. where the process is carried out beginning with the methylolation in a non-polar organic solvent, the methylolation is carried out in the presence of 0.1-0.3% by weight, based on the phenol employed, of Me++ ions, the etherification is effected at 95 DEG -120 DEG C. in the presence of one or more monohydric, dihydric or trihydric alcohols, with or without recycling of the distillate which passes over, and finally residual phenol in the products prepared by A. or B. is removed by evaporation in a thin film evaporator until the phenol content is less than 1% by weight. The phenol resol ethers prepared according to the invention are useful for the preparation of coating systems and for adhesives.

Abstract: Non-flammable insulating materials having good fire resistance and a density of from 80 to 230 g/l, which materials comprise A. from 99 to 80% by weight of inorganic lightweight particles, preferably expanded perlite or vermiculite, B. from 0 to 20% by weight of fibrous or granular inorganic additives and C. from 1 to 20% by weight of a heat-resistant organic high molecular weight binder, preferably a phenol-formaldehyde condensate, and which contain, as an additional binder C' to prevent water absorption, from 0.2 to 4% by weight of an alkylphenol/phenyl/formaldehyde condensate. The materials may be used as heat insulating materials or building materials.

Abstract: Phenol resins which are modified with compounds possessing amide and/or imide groups and are based on phenol resol ethers bonded via o,o'-methylene ether groups, and a process for their preparation. The novel modified phenol resol ethers are useful for the preparation of coating systems, in particular as crosslinking agents for cathodic electrocoating binders, and for the preparation of adhesives and rubber assistants.
