A Zn2+-induced reactive separation method for the purification of β-bromoethylbenzene from α-β-bromoethylbenzene mixtures is discovered, where the selective decomposition of α-bromoethylbenzene follows a radical mechanism. Zn2+ facilitates the homolysis of...

The free radical polymerization of the vapours of vinyl chloride, acrylic nitrile, styrene, butadiene and methyl isopropenyl ketone has been investigated using methyl radicals from photo-decomposing acetone. Although all the reactions do not exhibit ideal behaviour it is possible by the application of kinetic methods to measure the ratio of the propagation to the termination coefficients for these polymerization reactions. In this way relative values of the quantitative tendency for a molecule to polymerize by a free radical mechanism can be computed.

A newly-developed metal-carbene radical polymerization mechanism is proposed for poly(imidazole-Pd)-mediated carbene polymerization, which could produce stereoregular polycarbenes besides atactic polycarbenes.
