Abstract

1487120 Halogen - containing monomers BAYER AG 21 May 1975 [28 June 1974] 21779/75 Heading C3P [Also in Division C2] Flameproof polymers are obtained by using as a comonomers a compound of the formula where Hal is Cl or Br, X is H, Cl or Br, at least one X is Cl or Br and at least one of X and Hal is Br. Examples describe the production of terpolymers of styrene, acrylonitrile and 2,4,5-tribromo-α-methylstyrene.
