Abstract: Foams having a density of from 0.1 to 1.0 g/cm and based on aromatic polyether ketones and other thermoplastic polymers having a high melting point are obtained by melting an intimate mixture of the polymer and from 0.5 to 10% by weight of an aliphatic or aromatic di- or polycarboxylic acid which undergoes a weight loss of at least 50% on heating to from 130 to 300 DEG C with elimination of gaseous decomposition products, and cooling the product with simultaneous shaping.

Abstract: Expandable polymers in particle form for the preparation of foams having high heat distortion resistance contain from 20 to 94.9% by weight of a styrene polymer, from 0.1 to 75% by weight of a polyphenylene ether and from 5 to 20% by weight of a blowing agent mixture of aliphatic or cycloaliphatic hydrocarbons on the one hand and aromatic hydrocarbons, alcohols, ketones, ethers, esters and/or chlorohydrocarbons on the other hand.

Abstract: Flame-resistant polyurea foams are produced by reacting organic polyisocyanates with water in the presence of catalysts, assistants, additives and borax as flameproofing agent, expediently in an amount of from 150 to 400 parts by weight per 100 parts by weight of organic polyisocyanate. The polyurea foams filled according to the invention with borax have densities of from 60 to 160 kg/m and are suitable for the insulation of buildings and means of transport.

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: Finely divided, expandable styrene polymer for the prepn. of foamed bodies contains 0.0001-0.2% calcd. on the styrene polymer, of a nucleating agent for the expandable polystyrene, in inhomogeneous distribution, the nucleating agent being present in only a narrow marginal zone of the particle, the interior of the particle being free from nucleating agent. Used as esp. effective heat-conducting matl.; after foaming, each particle contains internally 5-7 cells) mm, whilst the narrow marginal zone shows a much larger cell count.

Abstract: (Co)polymerisation of styrene or mixtures thereof with 50% or less of comonomer(s) is carried out in suspension, in presence of a foaming agent and a suspension agent and 0.01 to 0.3%, with respect to weight of monomer(s) of a polysiloxane. The (co)polymer obtained may be coated with an emulsifier. Addition of the polysiloxane results in production of a finely divided polymer having excellent flow characteristics without tendency to agglomeration of the particles. Esp. suitable for prodn. of thin-walled foamed mouldings having homogeneous structure and good mechanical strength.
