Abstract
Different aspects of radical polymerization have been investigated in the author&s laboratory.1) Radical oligomerization has been studied by GC‐MS and some kinetic parameters obtained in this way (chain transfer and reinitiation constants, reactivity ratios) compared with the results of classical experiments.2) Star‐shaped polymers have been obtained by using a series of polyfunctional chain transfer agents; the experimental results agree very well with the theoretical expectations. 3) A reexamination of the copolymerization equation showed that the steady‐state assumption is not a necessary condition for the kinetic derivation and that all approaches are conceptually equivalent. 4) The structure and the 2D NMR spectra of hemiisotactic polypropylene obtained by radical inclusion polymerization are discussed.Funding Information
