| Abstract: | Allyl allyl sulfonate (AAS) has been polymerized under the influence of azobisisobutyronitrile to low molecular weight polymers containing cyclic structures. This is in contrast to the behavior of allyl ethane sulfonate (AES) and of propyl allyl sulfonate (PAS) which did not polymerize under the same conditions. AAS has been copolymerized with styrene, methyl acrylate, and vinyl acetate. The following copolymerization reactivity factors have been found: rAAS 0.01 ± 0.01 rstyrene 13 ± 1 rAAS 0-37 ± 0.09 rmethyl acrylate 5.3 ± 0-7 rAAS 1.54 ± 0.08 rvinyl acetate 0.5 ± 0.15 The results indicate that AAS has a higher reactivity than AES or PAS. |
