Abstract: | Linear polyacroleins prepared by anionic polymerization give the structural repeat units of the types documentclass{article}pagestyle{empty}begin{document}$ rlap{--}[{rm CH}left( {{rm CHO}} right)hbox{--} {rm CH}_{rm 2} {rm rlap{--} ], rlap{--} [CH}_{rm 2} hbox{--} {rm CH}left( {{rm CHO}} right)rlap{--} ], $end{document} and documentclass{article}pagestyle{empty}begin{document}$ rlap{--} [{rm CH}left( {{rm CH}hbox {rm CH}_2 } right)hbox{rm Orlap{--} ]} $end{document} without any cyclization. Analysis of these polymers by several methods reveal the nature and amount of each structural species, and an estimation of their distribution along the polymeric chain. |
