Abstract:
A flame retardant composition consisting essentially of (a) 30 to 90 weight percent olefin-alkoxy silane copolymer derived from an .alpha.-olefin having from 2 to 8 carbon atoms and 0.25 to 20 percent by weight, based on the weight of the copolymer, of an unsaturated alkoxy silane of the formulaR*--Si(R**).sub.a (Y).sub.3-awherein R* is an ethylenically unsaturated hydrocarbon radical having from 2 to 6 carbon atoms, R** is a hydrocarbon radical having from 1 to 10 carbon atoms, Y is an alkoxy group having from 1 to 4 carbon atoms and a is an integer from 0 to 2; (b) 5 to 40 weight percent of a brominated aromatic compound selected from the group consisting of decabromodiphenyl oxide and decabromodiphenyl ethane, (c) 1 to 20 weight percent antimony trioxide; (d) 0.01 to 2.5 weight percent silanol condensation catalyst; and (e) 1 to 40 weight percent magnesium hydroxide.
