ABSTRACT
It is the size of macromolecules that gives them their unique and useful properties. Size allows polymers to act more as a group so that when one polymer chain moves, surrounding chains are affected by that movement. Size also allows polymers to be nonvolatile since the secondary attractive forces are cumulative (e.g., the London dispersion forces are about 8 kJ/mole per repeat unit), and because of the shear size, the energy necessary to volatilize them is sufcient to degrade the polymer.
