Abstract:
The present invention relates to a method of preparing a vinyl chloride-based polymer, and more specifically, to a method comprising the steps of, (S1) preparing a mixture in which a first protective colloid auxiliary agent and a chain regulator are mixed; (S2) preparing a second protective colloid auxiliary agent including the chain regulator activated by stirring the mixture prepared in step (S1); and (S3) performing polymerization by adding a vinyl chloride-based monomer and a polymerization initiator in the presence of the second protective colloid auxiliary agent prepared in step (S2).

Claim (Index 8):
The method of  claim 1 , wherein the amount of the chain regulator is 0.01 parts by weight to 0.5 parts by weight based on 100 parts by weight of the vinyl chloride-based monomer.
