Reactions, classification polyaddition/polycondensation

Until recently it has been customary to classify synthetic polyreactions as polymerb.ations, polycondensations and polyadditions [1]. According to the lUPAC nomenclature [2] the term polymerization is superior to the concepts of addition polymerization and condensation polymerization. Both these subordinate terms are very broadly defined and so far the classification of reactions bearing the features of polymerization and polycondensation is rather arbitrary. Only addition polymerizations are treated in this book. Processes of the polycondensation type are not described.
