Abstract

Jojoba wax was chemically bonded to a polystyrene matrix via a stable C-C covalent bond. This was achieved by binding allyl-brominated jojoba derivatives to lithiated cross-linked polystyrene-2% divinylbenzene or XAD-4 polymeric beads via a nucleophilic substitution reaction. The double-bond regions in the jojoba wax were preserved. A side reaction that accompanied the nucleophilic substitution was HBr elimination, which produced diene and triene systems in the bound jojoba. Phosphonation and sulfur chlorination at the double bonds of the jojoba wax, bonded to the polystyrene matrix, were also performed.
