VINYL CHLORIDE POLYMERIZATION PROCESS AND PVC OBTAINED WITH SAID PROCESS

摘要

Process for the suspension polymerization of vinyl chloride,either pure or mixed with other monomers, to produce PVC resins. Theprocess uses, as suspending agent, a newly structured polyvinyl alcohol, soas to obtain PVC resins substantially exempt from closed cells and havingan improved thermal stability, no electrostatic charges and a low contentof ions of alkaline or earthy-alkaline metals, which make them particularlysuited for use as insulating materials in the electrical field.
