    摘要: The invention relates to a halogen-free flame retardant obtainable by polycondensation of phosphoric monomers with esterifying monomers. The phosphoric monomer is an adduct of 9,10-dihydro-9-oxa-10-phospha-phenanthrene-10-oxide (DOPO) and ring-substituted DOPO derivatives to unsaturated carboxylic acids. Monovalent and polyvalent alcohols are used as esterifying monomers. The flame retardant has an average molecular weight of more than 20,000 and an average degree of polymerization Pn of at least 55, and is preferably used for the production of polyamide fibers and polyester fibers by melt spinning.

    摘要: The invention relates to a method for preparing halogen-free flameproof epoxy resins, in which a halogen-free epoxy resin is reacted with a polyfunctional aldehyde or ketone and a phosphinic acid derivative, wherein the phosphinic acid derivative contains at least one P—H-active structural unit of the formula ═PH(O) and is used in an amount equivalent to the polyfunctionality of the aldehyde or ketone, to a halogen-free flameproof epoxy resin obtainable by this method, to the use of the epoxy resin as a base material for the manufacture of printed circuit boards and printed circuits and to intermediates used to prepare the epoxy resins.
