Joel R. Judah M.D.,Peter V. Draganov M.D.ions with the aim of establishing the general physicomechanical properties are somewhat fewer. Undoubtedly the questions to be answered about the mechanism are of fundamental interest, but the position of alternating polymers in the general scheme of polymer physical properties should merit equal at

Principles of Alternating Copolymerization,1930s. During that early period it was quickly recognized that copolymerization reactions possessed unique features which distinguished them from homopolymerizations and also made their interpretation more complex. It was observed that the composition of a copolymer could not necessarily be expected
