摘要: Abstract The addition of mineral acid to solutions styrene in dioxan enhances the radiation polymerisation yield polystyrene. Gel permeation chromatographic analysis resulting homopolymer shows that Mn values are significantly reduced by inclusion. When is carried out presence a trunk polymer such as cellulose or polyethylene (i.e. grafting conditions), same effect on observed monomer solution. A mechanism for this both and proposed based formation shorter chain oligomers. This has been extended monomer/solvent systems other than also shown be consistent with previously reported general effects radiolysis binary mixtures.
