Boric acid and diethanolamine intermediates were used to synthesize a boric acid diethanolamine ester Ⅰ.With maleic anhydride acylation,it occurred acylation in the N,N-Dimethylformamide solvent.It synthesized boric acid esters Ⅱ containing a polymerizable double bonds.Within a single molecule into boron nitride,as well as carboxyl,unsaturated double bond,amide bond and other active groups,a good coupling agent application performance could be achieved.Boric acid ester polymer was used in PA-6/square-shaped zinc oxide(T-ZnO) whisker system.Mechanical properties have greatly improved.From the SEM of the impact fracture surface of the spline,the conclusions were gained that zinc oxide whisker,which was surface treated by Ⅱ,was found and a part of the whisker was coated by the matrix resin.And the better interface layer which was formed between the whisker and the matrix played a good role in the effect of coupling agent.%以硼酸和二乙醇胺为原料合成中间体硼酸二乙醇胺酯,将其与马来酸酐在N,N-二甲基甲酰胺溶剂中发生酰化反应,合成含有可聚合双键的硼酸酯.在同一个分子内引入硼氮两元素,以及羧基、不饱和双键、酰胺键等活性基团,以达到良好的偶联剂应用性能.将可聚合硼酸酯应用于PA-6/四角状氧化锌（T-ZnO）晶须体系中,力学性能显著提高,从样条冲击断面的扫描电镜中可以看出,氧化锌晶须经过可聚合硼酸酯表面处理后,部分晶须被基体树脂包覆,晶须与基体间形成了良好的界面层,很好的起到了偶联剂的效果.
