Abstract

The invention belongs to the technical field of resin synthesis, and in particular relates to a vinyl chloride polymerization terminator as well as its preparation method and application. The raw material consists of diethylhydroxylamine, zinc acetylacetonate, triethylene glycol ether-bis(3-tert-butyl-4-hydroxy-5-methylphenyl) propionate, deionized water and emulsifier polyoxyethylene Composition of Sorbitan Trioleate. The vinyl chloride polymerization terminator of the present invention has the advantages of high termination efficiency, good thermal stability and transparency, and can endow resin products with lower yellowness index, higher light transmittance and lower haze, so that PVC products have excellent transparency; the prepared vinyl chloride polymerization terminator is suitable for the polymerization termination of food and medical PVC resins.

Description

technical field [0001] The invention belongs to the technical field of resin synthesis, and in particular relates to a vinyl chloride polymerization terminator as well as its preparation method and application. Background technique [0002] The terminator stops or significantly reduces the reaction rate by combining with the residual initiator active free radicals and the residual initiator to form an inactive compound. It can effectively protect the polymer from being heated in the process after stripping. Oxygen aging damage. The terminator is added when the polymerization reaction reaches the set end point, commonly used terminators include bisphenol A, acetone thiosemicarbazone, BHT and the like. A single terminator is often unable to meet the requirements of efficiently terminating the polymerization reaction and improving the thermal stability of the resin at the same time. The terminator is developing towards the functional composite direction of both chain terminati...
