High-resolution NMR spectra of the polysulfones of six monolefins

100-MHz NMR spectra are reported for solutions of the 1:1 copolymers of sulfur dioxide with hex-1-ene, cis- and trans-but-2-enes, cyclohexene, cyclopentene, and norbornene, including the deuterated polymers made from hex-1-ene-2-d₁, cis- and trans-but-2-ene-2,3-d₂, and cyclohexene-3,3,6,6-d₄. The resolution of the spectrum of poly-(hex-1-ene sulfone) was very poor in CCl₄ as solvent but good in polar solvents. The main-chain CH₂ protons are nonequivalent, and their chemical shifts show sensitivity to dyad structure; the α-CH₂ protons are also non-equivalent. The spectra of most of the other polymers are discussed in terms of possible preferential modes of addition as well as tacticity effects.
