Abstract: Synthetic plastic materials for the manufacture of extrusion, injection and press forms are described, which are prepared from elastomers as well as mixed- and copolymers thereof with thermoplastic properties and liquification products from extractive coal hydrogenation which are residues with a softening point between 50.degree. and 150.degree. C. Polar, aromatic or cyclic groups in the elastomer component increase the compatibility of the coal liquification residue with the elastomer and improve the mechanical properties of the products.
Abstract: Synthetic form masses are described which are derived from thermoplastic polyolefins as well as mixed and copolymerisates thereof and a coal liquification product. The coat liquification product is a residue which precipitates out during extractive hydrogenation and has a softening point between 70.degree. and 200.degree. C. The thermoplastic polyolefin contains a component of polar, aromatic or cyclic monomers, which improve the compatibility of the components in the mixture. The form masses from this mixture, which may include filler material, have excellent tear resistance properties.
Abstract: The present invention relates to new azulmic acids stabilized by condensation with carbonyl compounds, several processes for their preparation and their use for various purposes.
Abstract: Compositions for forming carbon-containing refractory brick or shape comprising a refractory filler, a binder for said filler and a hardening agent for said binder, said binder comprising a mixture of polymers formed by the homopolymerization of resorcinol. Compositions for forming a carbon-containing refractory brick or shape as above described are also disclosed in which a basic refractory filler is employed and hardening agents are unnecessary. Methods of forming carbon-containing refractory brick or shape are also disclosed involving milling of a dry binder comprising a mixture of polymers formed by the homopolymerization of resorcinol with the refractory filler or mixture of a solution of such a binder material with the refractory filler, either of which may be conducted at ambient temperature.

Abstract: This invention relates to hot melt adhesive compositions which include a highly unsaturated hydrocarbon rubber, about 5 to about 100 parts by weight of a neutralized sulfonated elastomeric polymer per 100 parts by weight of the highly unsaturated hydrocarbon rubber, wherein the neutralized sulfonated elastomeric polymer has about 5 to about 50 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated elastomeric polymer, and about 25 to about 200 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, aliphatic dienes and mono- and di-olefins, cyclic olefins of 5 or 6 carbon atoms and hydrogenated polycyclics per 100 parts by weight of the highly unsaturated hydrocarbon rubber.
Abstract: Curable polymer concrete compositions suitable for articles of construction comprise (1) a minor amount of a polyester resin composition, (2) a major amount of an aggregate blend comprising (a) sand and (b) fly ash and (3) a free-radical curing agent.
