Modification of Epoxy–bisphenol a Resin with Tetrachlorinated Bicyclic Compounds Containing Dicarbonyl Bridges

Abstract

As is known, polychlorinated bicyclic compounds are widely used as monomers and modifi ers for the production of heat and fi re-resistant polymeric materials and elastomers, and also fi reproofi ng additives to fl ammable thermoplastic materials. The fi reproofi ng action of polychlorinated compounds is connected with the fact that, during heating, they split off atomic chlorine, which is an effective fi re retardant. Their introduction into epoxy resins makes it possible to produce heat-resistant composites [1-5].
