    摘要： Provided are a vinyl chloride-based resin formed by polymerization of vinyl chloride-based small seed particles having an average particle diameter range of 0.15 μm to 0.5 μm prepared by emulsion polymerization and vinyl chloride-based large seed particles having an average particle diameter range of 0.51 μm to 0.8 μm prepared by micro-suspension polymerization, in which a content ratio (weight ratio) of the large seed particles to the small seed particles is in a range of 1 to 2, and a method of preparing the vinyl chloride-based resin. Excellent low viscosity characteristics of the vinyl chloride resin at high and low shear rates may be obtained by controlling the particle size of the small seed prepared by emulsion polymerization.

    摘要翻译： 本发明提供一种氯乙烯系树脂，其通过聚合具有通过乳液聚合制备的平均粒径范围为0.15μm至0.5μm的氯乙烯基小种子颗粒和平均粒径范围为氯乙烯的大型种子颗粒 通过微悬浮聚合制备的0.51μm〜0.8μm，其中大种子颗粒与小种子颗粒的含量比（重量比）在1至2的范围内，以及制备氯乙烯基 树脂。 通过控制通过乳液聚合制备的小种子的粒度，可以获得高低剪切速率下氯乙烯树脂的优异的低粘度特性。
