Disclosed are brominated azido fire-retardants having the formula (Br).sub.x --R--[(R').sub.n --A].sub.y Where R is an organic radical; R' is selected from ##EQU1## --O(R"-O).sub.b --R"--, ##EQU2## where R" is selected from alkylene, cycloalkylene, alkylene cycloalkylene, arylene, alkylene arylene, and the foregoing radicals with bromo substituents, and b is an integer from 1 to 10; A is selected from ##EQU3## and --SO.sub.2 N.sub.3 where z is 0 or 1; x is at least 3; n is 0 or 1; and y is an integer from 1 to 100. Also disclosed is the process of preparing fire-retardant natural and synthetic fibers and films which comprises contacting the surface of said fiber or film with a brominated azido fire-retardant and initiating reaction of the fire-retardant with the fiber or film by heat or irradiation.
本发明涉及一种具有以下结构式的溴化叠氮阻燃剂:(Br).sub.x --R--[(R').sub.n --A].sub.y 其中R是有机基团;R'从以下选取:##EQU1## --O(R"-O).sub.b --R"--, ##EQU2## 其中R"从烷基、环烷基、烷基环烷基、芳基、烷基芳基以及具有溴代取代基的前述基团中选取,b为1至10的整数;A从以下选取:##EQU3## 和--SO.sub.2 N.sub.3,其中z为0或1;x至少为3;n为0或1;y为1至100的整数。本发明还揭示了制备阻燃天然和合成纤维和薄膜的方法,包括将所述纤维或薄膜的表面与溴化叠氮阻燃剂接触,并通过热或辐射引发阻燃剂与纤维或薄膜的反应。
