The examination of H 2 O 2 -initiated hydroxytelechelic polybutadienes polymerized by H 2 O 2 initiation by 1 H NMR and 13 C NMR allows the identification of three main primary alcoholic groups: α-unsaturated, β-substituted/α-unsaturated and γ-unsaturated. From 1 H NMR accumulated ...

It is observed that these three primary alcohol functions do not have the same reactivity towards hexamethyldisilazane as silylating agent.doi:10.1002/macp.1979.021801017Fages GenevièvePham Quang‐ThoHüthig & Wepf VerlagDie Makromolekulare Chemie...
The quantitative importance (several ppm) of the effect of solute–solvent van der Waals' interactions on the13C chemical shift is shown for a non polar solute,n-pentane, in solution in 17 solvents and in the gas phase. The van der Waals screening constant term is discussed in respect to...

As starting materials chloro-3-acetoxy-[or 3-(2,3)-epoxypropoxy]-propyldimethylsilanes ( 2 and 3 ) were prepared by hydrosilylation of the corresponding allylic derivatives with chlorodimethylsilane, and subsequently condensed with α-hydro-ω-hydroxyoligo- (or poly-) dimethylsiloxanes ( 1b ...
