Conversion of benzo[a]pyrene by alkylation of technical bitumens

Abstract

The studies showed an alkylating action of unsaturated polyester resins and polyethylene glycols heated at 140 to 160°C for 0.5 to 5 h without any catalyst added (except for curing agents in the case of unsaturated polyester resin). A considerable reduction of benzo[a]pyrene content by polyester resin was accompanied by a degrees of the softening point as well as by an increase in penetration and toluene insolubles. With polyethylene glycols, the benzo[a]pyrene content decreased as the molecular mass of the glycol was increased and the glycol content in the reaction mixture was raised. The chemical conversion of benzo[a]pyrene was evidenced by IR, ESR and 13C-NMR spectroscopies applied to model benzo[a]pyrene–polymer blends.
