Abstract
PURPOSE: Titled composition with excellent heat stability and workability in thermal processing, which is prepared by compounding a PVC of a specified or higher average polymerization degree, with a PVC of a low polymerization degree, having a bonded sulfur and hydroxy group in the molecule.
CONSTITUTION: A PVC of an average polymerization degree 100W600, having a bonded sulfur and hydroxy group in the molecule, is prepared, by the polymerization of a vinyl chloride monomer or an ethylenically unsaturated monomer copolymerizable with the vinyl chloride monomer, in the presence of a chain transfer agent containing sulfur and a hydroxy group (e.g., 2-mercaptoethanol or thiopropylene glycol). Then purpose PVC composition is obtained by mixing the PVC with a PVC of an average polymerization degree ≥600 in a ratio of about 5:95W 50:50.
