    摘要: Method for the preparation of a film forming flame retardant comprising nitrogen and silicon in its chemical composition, said method comprising the following steps: i. conversion of Z 1 moles of amine moiety, selected from the group of primary and secondary amine and covalently bound to Z 2 moles of one or more at least partially hydrolysable silane moiety, with Z 3 moles of a chemical substance selected from a group of chemical substances obtainable from carboxylic acids or carbonic acid and represented by formula (I), (II) or (III); ii. conversion with a with at least one HO-functionalized substance of formula (IV): M x (OH) y R 5 z . The resulting film forming flame retardant is contemplated.
