Summary:The present invention provides a method for preparing a vinyl chloride polymer, the method comprising a step for feeding a vinyl chloride monomer and a monomer represented by chemical formula 1 into a reactor, followed by polymerization, wherein the feeding amount of the monomer represented by chemical formula 1 is 1 to 4 parts by weight relative to 100 parts by weight of the vinyl chloride monomer, and the monomer represented by chemical formula 1 is continuously fed into the reactor. La présente invention concerne un procédé de préparation d'un polymère de chlorure de vinyle, le procédé comprenant une étape d'alimentation d'un monomère de chlorure de vinyle et d'un monomère représenté par la formule chimique 1 dans un réacteur, suivie d'une polymérisation, la quantité d'alimentation du monomère représenté par la formule chimique 1 étant de 1 à 4 parties en poids par rapport à 100 parties en poids du monomère de chlorure de vinyle, et le monomère représenté par la formule chimique 1 étant alimenté en continu dans le réacteur. 본 발명은 반응기에 염화비닐 단량체 및 상기 화학식 1로 표시되는 단량체를 투입하고 중합하는 단계를 포함하고, 상기 화학식 1로 표시되는 단량체의 투입량은 상기 염화비닐 단량체 100 중량부에 대하여, 1 내지 4 중량부이고, 상기 반응기에 상기 화학식 1로 표시되는 단량체를 연속 투입하는 염화비닐계 중합체의 제조방법을 제공한다.
