摘要： A method that is capable of producing a vinyl chloride-based polymer having excellent thermal stability without sacrificing productivity is provided. The method includes polymerizing a vinyl chloride-based monomer in the presence of a vanadium compound (A) represented by formula: Vi(═O)jZk (wherein i is an integer of 2 to 5, j represents 0 or 1, Z represents a ligand such as is an organic ligand that can bond to the vanadium atom via a hetero atom, and a plurality of ligands Z may be bonded together to form a ring that also includes the vanadium atom as a member of the ring, and k is an integer from 1 to 5), and in the presence of at least one aluminum compound (B).
