Vinyl chloride terminator and preparation method thereof

The invention relates to C08F2, in particular to a vinyl chloride terminator and a preparation method thereof. The vinyl chloride terminator comprises the following raw materials: a heat stabilizer, a polymerization inhibitor, an antioxidant, an emulsifier, a thickener and a regulator. The polymerization inhibition effect of the vinyl chloride polymerization reaction can be ensured, and the quality and the storage stability of the polymerization product are also improved, so that the obtained polymerization product is not easy to yellow and has relatively good mechanical properties; the adding sequence and the dripping rate of the raw materials in the preparation process of the terminator are controlled, so that the stability of the terminator is further improved. The terminator can be placed for a long time, can be stably stored after being placed at room temperature for one month, is suitable for polymerization reaction of various polyvinyl chloride, and is applied to the polymerization reaction of the poly
