WebElectron-transfer initiation also occurs in heterogeneous polymerizations involving dis- persions of an alkali metal in monomer. Initiation involves electron transfer from the metal to monomer followed by dimerization of the monomer radical–anion to form the propagating. ANIONIC POLYMERIZATION OF THE CARBON–CARBON DOUBLE BOND 415 Web6 sep. 2024 · The formation of stable covalent chemical bonds between the monomers sets polymerization apart from other processes, such as crystallization. Polymerization is important because it is the process by which plastics are made. It affects numerous aspects of everyday life, as anything to do with plastic, fabrics or elastomers involves …
WebThe reaction involves the mutual saturation of three unsaturated carbonyl groups. Condensation polymerization involves a similar joining together of molecules, but this time a simple molecule, such as water, is condensed out. Diethylene glycol, for example, can be made by heating glycol with a dehydrating agent.
