Investigation of the molecular characteristics of polyvinyl chloride obtained in presence of polyfunctional additives

Abstract The influence on the MMD of polyvinyl chloride of the addition during the course of polymerization of additives of polyfunctional monomers containing allyl groups and an allyl ester of methacrylic acid has been studied. A branchid polymer forms with a wide MMD and also a crosslinked polymer. Addition of triallyl isocyanurate raises the MM of polyvinyl chloride to a greater extent than does a monomer containing two allyl groups.
