The latter feature means the product-referred to here as poly(S-r-limonene)-is not as malodorous as in the original synthesis. Hasell and co-workers also showed that poly(S-rlimonene), as a soluble oligomer, can be used to coat silica gel for mercury sorption. The focus of this report, however, was primarily on the use of accelerators and catalysts in the copolymerisation of sulfur with alkene-containing monomers, and not mercury sorption.
