Unsaturated phosphate type polyether monomer and preparation method thereof
The invention provides an unsaturated phosphate type polyether monomer and a preparation method thereof. The unsaturated phosphate type polyether monomer is an esterification reaction product of a monomer I and a monomer II. The novel unsaturated phosphate type polyether monomer developed by the invention can be directly used for synthesis of a polycarboxylate superplasticizer, and the obtained polycarboxylate superplasticizer is widely concerned by the industry due to the special properties of low mixing amount, high water-reducing rate, good concrete workability, good dispersion retention ability, applicability at a low water/ash ratio and the like. In addition, the unsaturated phosphate type polyether monomer can also be applied to the field of daily chemicals and the like.
本申请提供一种不饱和磷酸酯型聚醚单体及其制备方法，该一种不饱和磷酸酯型聚醚单体是以下单体Ⅰ与单体Ⅱ的酯化反应产物。本发明开发的新型不饱和磷酸酯型聚醚单体可以直接用于聚羧酸减水剂的合成，所得聚羧酸减水剂由于其低掺量，减水率高，混凝土和易性好，分散保持能力良好，以及可以在低水/灰比下适用等特殊性能，受到业界的广泛关注。此外，该不饱和磷酸酯型聚醚单体还可以应用于日化领域等。
