Abstract
AbstractCrosslinking efficiency of isotactic polypropylene was studied as a function of the initiator used and of the reaction temperature. The decomposition rate of the initiator was found to be of prime importance for attaining the gel point. The over‐all efficiency of the process is strongly influenced also by the type of the formed primary radicals and the reaction temperature. The ratio of the number of broken and newformed bonds determined according to the Charlesby‐Pinner equation was found to be about 0.15 at high stationary macroradical concentration in the reaction system.
