Notes:
Samples of PVC, obtained by bulk polymerization were tested. Molecular weight distribution by nephelometric titration, number of branching by viscosity measurement, and density of the powders and films using a density gradient column were assessed. Microphotographs of the powders were taken. It was found that the average number of branching in 1000 monomer units is approximately proportional to the contact surface of the liquid and solid phase.
