介绍了PVC聚合用阴离子配位锌的合成工艺，研究了阴离子配位锌PVC热稳定剂最佳合成工艺条件：反应温度84℃，阴离子配位体为C7-9脂肪酸，辅助稳定剂为环氧棉籽油，添加配比为m（G7-9脂肪酸）：m（环氧棉籽油）=95：5，相转移催化剂确定为甲醇＋去离子水＋醋酸组合，pH值控制在6．3～6．5。
介紹瞭PVC聚閤用陰離子配位鋅的閤成工藝，研究瞭陰離子配位鋅PVC熱穩定劑最佳閤成工藝條件：反應溫度84℃，陰離子配位體為C7-9脂肪痠，輔助穩定劑為環氧棉籽油，添加配比為m（G7-9脂肪痠）：m（環氧棉籽油）=95：5，相轉移催化劑確定為甲醇＋去離子水＋醋痠組閤，pH值控製在6．3～6．5。
개소료PVC취합용음리자배위자적합성공예，연구료음리자배위자PVC열은정제최가합성공예조건：반응온도84℃，음리자배위체위C7-9지방산，보조은정제위배양면자유，첨가배비위m（G7-9지방산）：m（배양면자유）=95：5，상전이최화제학정위갑순＋거리자수＋작산조합，pH치공제재6．3～6．5。
The synthetic process of anion-coordinated zinc for PVC polymerization xs introduced. The best synthetic conditions of heat stabilizer anion-coordinated zinc for PVC were deter- mined by study： reaction temperature 84 ℃, C7-9 fatty acid as anion ligand, epoxy cottonseed oil as auxiliary stabilizer, addition mass ratio of C7-9 fatty acid to epoxy cottonseed oil 95 ： 5, combined phase transfer catalyst composed of methanol, deionized water and acetic acid, pH value 6.3-6.5.
