Regular comb macromolecule

Note 1 If the bchains between the branch points of the main chain and the terminal svhchains of the main chain are identical with respect to constitution and degree of polymerization, and the siAQ-chains are identical with respect to constitution and degree of polymerization, the macromolecule is termed a regular comb macromolecule. 

Polymer composed of regular macromolecules, regular star macromolecules, or regular comb macromolecules. 

An lUPAC publication (11) discusses both structure-based and source-based representations of comb polymers acomb polymer is described as a macromolecule comprising a main chain with trifunctional points from which linear side chains emanate. If the subchains between the branch points of the main chain and the terminal subchains of the main chain are identical with respect to constitution and degree of polymerization, and the side chains are identical with respect to constitution and degree of polymerization, the macromolecule is termed a regular comb macromolecule. If at least some of the branch points are of functionalities greater than three, the macromolecule may be termed a brush macromolecule.
