Abstract: New mono- or dialcohols of mononuclear, five-membered or six-membered, unsubstituted or substituted N-heterocyclic compounds which contain two NH-groups in the molecule, by reaction of mononuclear, five-membered or six-membered, unsubstituted or substituted N-heterocyclic compounds, for example hydantoin, barbituric acid, uracil, dihydrouracil, parabanic acid and the corresponding derivatives, with butene oxid, 1,2-cyclopentene oxide or 1,2-cyclohexene oxide to give monoalcohols or dialcohols. These compounds are useful as intermediates for the preparation of diglycidyl compounds as set forth in German Offenlegungsschrift No. 2,104,259.

Abstract: New mono- and dialcohols of binuclear, five-membered or six-membered, unsubstituted or substituted N-heterocyclic compounds, which contain two NH groups in the molecule, by reaction of binuclear, five-membered or six-membered, unsubstituted or substituted, N-heterocyclic compounds, such as bis-(hydantoin) or bis-(dihydrouracil) compounds, for example 1,1'-methylene-bis-(5,5-dimethylhydantoin), bis-(5,5-dimethylhydantoinyl-3)-methane or 1,1'-methylene-bis-(5,6-dihydrouracil) with ethylene oxide, for example ethylene oxide or propylene oxide, to give the corresponding monohydroxy or dihydroxy compounds. These compounds are useful as intermediates for forming diglycidyl ether resins as described in German Offenlegungsschrift No. 2,003,016.

Abstract: New diacrylates are obtained by a process in which oxalkylated uracils dihydrouracils are esterfied with acrylic acid and/or methacrylic acid, or transesterified with acrylic acid ester and/or methacrylic acid ester.The new diacrylates are low-viscous liquids, which can be easily processed by virtue of their consistency; and the polymerisates produced therefrom, are distinguished by good flexural strength and high transparency.

Abstract: Linear, thermoplastic polyesters based on terephthalic acid, ethylene glycol or 1,4-butanediol, which contain co-condensed chlorinated and/or brominated 1,3-bis-(hydroxyalkyl)-benzimidazolones, crystallize on stretching and are suitable for the manufacture of flame-resistant to flameproof fibers.

Abstract: The invention relates to new triglycidyl compounds of the formula: ##EQU1## wherein X represents a bivalent alkylene group required for the formation of a 5- or 6-membered heterocycle, and R represents hydrogen or an alkyl group having 1 to 4 carbon atoms.The new triglycidyl compounds are stable in storage and from them are obtained, after curing, synthetic materials having good mechanical strength and high dimensional stability under heat.

Abstract: Diepoxides manufactured by epoxidation of diacetals or diketals from .DELTA..sup.3 -cyclohexene-1,1-dimethanol or its homologues and dialdehydes or diketones which apart from the two aldehyde groups or keto groups only contain hydrocarbon radicals, for example the diepoxide of the formula ##SPC1##The new diepoxides couple good mechanical properties with a significantly higher heat distortion point according to Martens than the known epoxidised diacetals of similar constitution, in which the acetal groups are interrupted by an alkylene-oxyalkylene chain instead of by an alkylene chain which is free of ether oxygen.

Abstract: New diacrylates are obtained by a process in which oxalkylated bis-hydantoins are esterified with acrylic acid and/or methacrylic acid, or transesterified with acrylic acid ester and/or methacrylic acid ester.The new diacrylates are low-viscous liquids, which can be easily processed by virtue of their consistency; and the polymerisates produced therefrom, are distinguished by good flexural strength and high transparency.
