<p>1305834 Fire-retardant polymer compositions HOOKER CHEMICAL CORP 29 July 1970 [4 Aug 1969] 36781/70 Headings C3B C3C C3G C3P and C3R A fire-retardant polymeric composition comprises a polymer and an effective fire-retardant proportion of a compound of the formula where X is F, Cl or Br, Y is F, Cl, Br or alkyl, haloalkyl, alkoxy or haloalkoxy of 1-10 carbon atoms and R is H or alkyl of 1-6 carbon atoms. Examples relate to compositions containing ABS resin; a styrene-butadiene rubber; EPDM; butyl rubber and SBR sponge rubber. All of these compositions also contain antimony trioxide. Many other polymers which may be used in the compositions are referred to.</p> |
