Abstract
Molecular weights and their distributions of polycarbonate, prepared by the phosgenation process, were measured after melting. When the polymer was melted at the temperature lower than 320°C, the molecular weights decreased, showing some limiting values, and the shape of molecular weight distribution curves became somewhat sharper ones. The result could be explained as the influence of the amount of low molecular weight fractions.
The phenomenon of the Flory's “Random reorganization of molecular weight distribution”, was observed.
