采用来源于生物质资源的双酚酸为原料，利用界面聚合法合成新型阻燃剂聚双酚酸苯基磷酸酯(poly (DPA-PDCP)).探索了时间、催化剂用量、氢氧化钠用量等因素对其产率的影响，在优化的工艺条件下（室温、催化剂摩尔分数为0.04，nNaOH：nDPA = 3，反应时间为0.5 h），poly(DPA-PDCP)产率可达75%.当poly(DPA-PDCP)与APP以1: 4比例复配阻燃EVA，总添加量质量分数为30%时，EVA的氧指数达到25.7%；锥形量热测试表明最大热释放速率降低61%；TGA测试显示起始分解温度较纯EVA提高32 ℃，最大分解温度提高20 ℃，同时在600 ℃的残炭量质量分数高达27%.结果表明，poly(DPA-PDCP)与APP复配阻燃体系主要以固相阻燃机理为主；poly(DPA-PDCP)主要作为碳源，与APP配合使用时存在协同阻燃效应.
