In this study, a small amount of vinylphosphonic acid was used to produce fire‐retardant copolymers and terpolymers from acrylonitrile and methyl acrylate. The structures of copolymer and terpolymers were elucidated by ¹H‐NMR and phosphorous analysis. Thermal decomposition of vinylphosphonic acid‐containing copolymers and terpolymers started at lower temperatures than of poly(acrylonitrile‐co ‐methyl acrylate). Methyl acrylate contributes to the thermal resistance of the terpolymers. Poly(acrylonitrile‐co ‐methyl acrylate‐co ‐vinylphosphonic acid) with a phosphorous content about 0.25% burned at a slower rate and emitted less smoke compared to poly(acrylonitrile‐co ‐methyl acrylate). The burning tests showed that both copolymer and terpolymers containing vinylphosphonic acid behaved as a fire‐retardant polymer. The phosphonate and phosphonic acid groups in the copolymer and terpolymers accelerate the cyclization of nitrile groups and inhibit the fire in the gas phase. Nanofibers were successfully produced by the electrospinning method from the copolymers and terpolymers containing vinylphosphonic acid moiety.

乙烯基膦酸，丙烯腈和丙烯酸甲酯的聚合物及其纳米纤维

在这项研究中，少量的乙烯基膦酸被用于由丙烯腈和丙烯酸甲酯生产阻燃共聚物和三元共聚物。通过¹ H-NMR和磷分析阐明了共聚物和三元共聚物的结构。含乙烯基膦酸的共聚物和三元共聚物的热分解起始温度低于聚（丙烯腈-丙烯酸-丙烯酸甲酯）共聚物。丙烯酸甲酯有助于三元共聚物的耐热性。聚（丙烯腈-共-甲基丙烯酸酯-共-vinylphosphonic酸）与约0.25％的磷含量烧以较慢的速率和发射相比少聚抽烟（丙烯腈共-丙烯酸甲酯）。燃烧测试表明，含有乙烯基膦酸的共聚物和三元共聚物均表现为阻燃聚合物。共聚物和三元共聚物中的膦酸酯和膦酸基团加速腈基的环化并抑制气相中的火焰。通过电纺丝法成功地从包含乙烯基膦酸部分的共聚物和三元共聚物中制备了纳米纤维。
