Abstract:
PROBLEM TO BE SOLVED: To provide a stabilizer against the actions of light, oxygen, and heat.SOLUTION: There is provided use of such polynuclear phenolic compounds as stabilizers to stabilize inanimate, organic materials against the action of light, oxygen, and heat, as have up to 20 benzene nuclei in the molecule and are obtained by the reaction of tetrahydrobenzoxazine expressed by general formula (I), with one or plural, identical or different phenols expressed by specific formulae and/or with one or plural, identical or different tetrahydrobenzoxazines [in the formula, substituent Ris a (1-3,000)C hydrocarbyl group, which may be interrupted with one or plural heteroatoms selected from the group constituting of O and S, and/or with one or plural NRgroups, wherein Ris hydrogen or a (1-4)C alkyl group, and substituents R, R, R, and Rare each independently, a hydrogen atom, a hydroxy group, or a (1-3,000)C hydrocarbyl group, which may be interrupted with one or plural heteroatoms selected from the group consisting of O and S, and/or with one or plural NRgroups, wherein Ris the same as defined above].
Abstract:
The invention relates to a synergistic mixture comprising between 1 and 99.9 wt. % of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom can be combined to form a five-membered, six-membered, or seven-membered ring and the benzene nucleus can still carry substituents on at least one of the free positions, and between 0.1 and 99 wt. % of sulphurous organic compounds having an anti-oxidant action. The synergistic mixture is suitable as a stabiliser for stabilising inanimate organic material, especially mineral oil products and fuels, against the effects of light, oxygen, and heat.
Abstract:
The invention relates to an additive formulation for the anti-static finishing and improvement of the electrical conductivity of inanimate organic material made of (A) 1 to 50% by weight of an olefin-sulfur dioxide copolymer, (B) 1 to 50% by weight of a compound having alkaline nitrogen atoms with longer-chained hydrocarbon groups with at least 4 carbon atoms or an equivalent structural element, which ensures the solubility of (B) in the inanimate organic material, (C) 0.1 to 30% by weight of an acid soluble in oil, and (D) 1 to 80% by weight of an organic solvent with a high boiling point, wherein at least 80% by weight of the molecule types have a boiling point that is higher than 150ºC at normal pressure.

Abstract:
The present invention relates to a process for producing composite materials which consist essentially of a) at least one oxidic phase and b) at least one organic polymer phase, by copolymerizing - at least one compound A selected from aryloxy metallates, aryloxy semimetallates and aryloxy esters of non-metals which form oxo acids and are different from carbon and nitrogen, with - at least one compound B selected from formaldehyde and formaldehyde equivalents, in a reaction medium which is essentially anhydrous, the compound B being used in an amount such that the molar ratio of formaldehyde to the aryloxy groups in the compound A is at least 0.9:1.
