The stoichiometry is simple: This conversion can be induced by a variety of catalysts including free radicals, acids, carbanions and metal complexes.
Examples of such polyolefins are polyethenes, polypropylene, PVC, Teflon, Buna rubbers, polyacrylates, polystyrene, and PCTFE.
One universal distinction between polymerization types is development of molecular weight by the different modes of propagation.
Since addition polymerization has rapidly growing chains and free monomer as its reactants, and condensation polymerization occurs in step-wise fashion between monomers, dimers, and other smaller growing chains, the effect of a polymer molecule's current size on a continuing reaction is profoundly different in these two cases.
They left the reaction vessel overnight, and the next morning they found a small amount of a white waxy solid.
