Abstract
New, halogenated bis-acrylates are obtained when a N,N'-di-(hydroxyalkyl)-benzimidazolone which is halogenated in the nucleus is esterified with acrylic acid or methacrylic acid or an acrylate or methacrylate. The new halogenated bis-acrylates are valuable comonomers since they contain halogen bonded in a stable manner, can readily be copolymerized with polymerizable compounds and are suitable for the manufacture of flame-resistant polymers.
