Polymerization of Isoprene in Ethylacetate in the Presence of Hydrogen Peroxide

Orders by monomer and initiator at polymerization of isoprene in solution of ethylacetate under the action of hydrogen peroxide have been determined. The order by monomer is equal to 1.49 ± 0.03, by initiator – 0.46 ± 0.05. Unlike polymerization in solution of isopropyl alcohol, a process in ethylacetate proceeds in homogeneous solution.

Synthesis and Characterization of Oligoisoprene obtained in Allyl Alcohol Solution in the Presence of Hydrogen Peroxide

The cooligomers of isoprene and allyl alcohol under the action of hydrogen peroxide have been synthesized. Using a solvent of variable composition isopropyl alcohol–allyl alcohol showed that the cooligomer yield doesn’t depend on a ratio of solvent composition. Polymerization of allyl alcohol itself doesn’t take place. The determination of molar weights and hydroxyl group contents in the cooligomers obtained in both alcohols showed that the cooligomer obtained in the allyl alcohol has an increased functionality 3.5 against 2 in single isopropyl alcohols
