The invention relates to a high-reverse-shift elastic biomass water-based PU (Polyurethane) resin and formula development technology, in particular to the field of polymer materials, in particular to a water-based biomass polyurethane emulsion, and particularly relates to polyester polyol prepared by taking 2-methylsuccinic acid (2-mSA) as a polymeric monomer as the polymeric monomer. The invention also relates to a preparation method of the water-based biomass polyurethane emulsion. 本发明涉及高反拨弹性生质水性PU树脂与配方开发技术，具体涉及聚合物材料领域，具体而言系涉及一种水性生质聚氨酯乳液，尤其系涉及将包含2-甲基丁二酸(2-mSA)作为聚合单体制得的聚酯多元醇作为聚合单体。本发明亦涉及一种水性生质聚氨酯乳液的制备方法。
