Flame retardancy of epoxy resin with phosphorus-containing reactive amine and clay minerals

Autor: N. Tóth, K. Kiss, Andrea Toldy, Gy. Marosi, Péter Anna, Gy. Keglevich

Publikováno v: Polymers for Advanced Technologies. 17:778-781

Flame retardant effect of newly synthesized phosphorus-containing reactive amine, which can be used both as crosslinking agent in epoxy resins and as flame retardant, was explored. The effect of montmorillonite and sepiolite additives on thermal stab

Selective phosphorylation of hydroxyphenols for forming reactive flame retardants

Autor: M. Le Bras, Andrea Toldy, Péter Anna, Gy. Keglevich, X. Almeras, Gy. Marosi

Publikováno v: Polymer Degradation and Stability. 82:317-323

Monophosphorylated hydroxy phenols were synthesized in a selective way and incorporated in different percentages into epoxy resins as reactive flame retardants. The LOI values of the epoxy resin samples could be increased this way up to 28%. The DSC

PHOSPHORYLATION OF PHENOLS AND NAPHTHOLS BY PHENYLMETHYLENEPHOSPHINE OXIDE GENERATED BY THE THERMOLYSIS OF A 2-PHOSPHABICYCLO[2.2.2]OCTA-5,7-DIENE 2-OXIDE

Autor: Laszlo Toke, András Dobó, Gy. Keglevich, Z. Nagy, Helga Szelke

Publikováno v: Synthetic Communications. 31:1737-1741

A simple method utilising a low-coordinate phosphorus species is described for the phosphorylation of a series of phenols and naphthols to afford aryl methylphenylphosphinates in reasonable yields.

Convenient Method for the Reduction of the Double-Bond of Cyclic Vinylphosphine Oxides Using Borane

Autor: András Dobó, Zs. Böcskei, Gy. Keglevich, L. Toke, M. Fekete, Tungalag Chuluunbaatar

Publikováno v: Synthetic Communications. 30:4221-4231

The electronpoor double-bond of cyclic vinylphosphine oxides (1, 3 and 4) is easily reduced by borane in a selective manner to give the corresponding saturated derivatives (2, 4 and 5, respectively) Under forcing conditions, change of the functionali
