Abstract

original image

A matter of phis: The size of macromolecules is determined by the “universal calibration” based on the Flory–Fox equation (see scheme). The effect of the segmental density of real branched systems on this equation is investigated. To study this effect, accurately prepared polymers with discrete molecular properties were characterized in detail and precisely evaluated.
