ON THE MECHANISM OF POLYETHYLIDENE FORMATION FROM DIAZOETHANE.
Abstract
A suitable mechanism of reaction for the processes leading to amorphous and crystalline polyalkylidenes from the metal catalyzed decomposition of diazoalkane solutions is proposed and discussed on the basis of the experimental evidences as obtained: from the kinetic investigation of the formation of amorphous and crystalline polyethylidene from the gold catalyzed decomposition of ethyl ether solutions of diazoethane; from the investigations on the degree of polymerization of polyethylidene, as related to diazoethane and catalyst concentrations; from the data upon the temperature dependence of the rates of formation of both amorphous and crystalline polyethylidene; from the temperature dependence of the degree of polymerisation of polyethylidene; from the results of the quantitative determination of the terminal double bonds on the vinyl type in the polyethylidene chain.
