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: The invention relates to reinforced polyoxymethylene moulding compositions having improved thermostability comprising (A) at least one polyoxymethylene homopolymer and/or copolymer, (B) at least one reinforcing material, preferably glass fibres or textile sheet-like structures made from glass fibres, (C) at least one alkoxymethylmelamine and (D) optionally additives, which contain, in order to improve the heat resistance, reduce the tendency to discoloration and minimise the free formaldehyde content, as (E) additive, at least one alkaline earth metal glycerophosphate and/or magnesium silicate, expediently in an amount of from 0.01 to 2% by weight, based on the weight of components (A) and (B). In order to prepare the reinforced moulding compositions, the formative components are expediently melted together in an extruder at temperatures of from 150 to 260 DEG C. The reinforced poloxymethylene compositions are suitable for the production of mouldings used, for example, in the automotive, electrical appliance and electronics industries.

Abstract: Finely divided expansible styrene polymer particles, for the prodn. of foram mouldings, contain 0.0001-0.2 phr of a nucleating agent (I) in non-homogeneous distribution, (I) being situated only in a thin band at the surface of the particles and virtually absent in the interior. Mouldings obtd. from the particles can be demoulded after a short dwell-time in the mould, have very low thermal conductivity (due to the coarse internal pore structure), have good dimensional stability (i.e. no lateral depression) and have homogeneous density.
