Branched polymers. II—Dimensions in non-interacting media

Theoretical expressions for the mean square radii of some random flight ‘comb’ type branched molecules are derived. The structures considered consist of linear backbone chains to which linear side chains are attached by one end at various positions along the backbone. Expressions for the (light scattering) z-average radii of some mixtures of star and comb molecules likely to be obtained in the syntheses of these materials are also presented.
