regular polymer

A polymer composed of regular macromolecules, regular star macromolecules or regular comb macromolecules. A polymer consisting of star macromolecules with arms identical with respect to constitution and degree of polymerization is considered to be regular; See: star macromolecule, [note 2]. Analogously, a polymer consisting of comb macromolecules with the sub-chains between the branch points of the main chain and the terminal sub-chains of the main chain identical with respect to constitution and degree of polymerization and the side-chains identical with respect to constitution and degree of polymerization is considered to be regular; See: comb macromolecule, [note 1].
