Abstract

An acrylate-phosphorus-based monomer, bis[2-(methacryloyloxy)ethyl] phosphate (BMEP), is successfully prepared by the reaction of 2-hydroxyethyl methacrylate with phosphorus pentoxide (P₂O₅). The chemical structure of BMEP is elucidated via ¹H NMR, ³¹P NMR, MS, and FTIR analyses. Subsequently, an aliphatic urethane acrylate oligomer (AUA) reacts with isoprenyl methacrylate (IPEMA), producing a novel polymer (UAIPA).This polymer is further modified by incorporating BMEP at concentrations of 2 %, 4 %, and 6 %, yielding phosphorus-containing polymers. These polymers are characterized using FTIR, XRD, SEM, DSC, TGA, and EDS. They demonstrate excellent corrosion inhibition properties, achieving an efficiency of approximately 99 %. Additionally, the adhesion performance of the phosphorus-containing polymers on metallic surfaces is evaluated, yielding a 5B rating. The high adhesion strength supports their potential as effective anti-corrosive coatings. In conclusion, the novel phosphorus-functionalized acrylate polymer exhibits exceptional multifunctional properties, making it highly suitable for advanced coating applications and opening up new possibilities in materials science and polymer chemistry.

光固化涂料中磷功能化丙烯酸酯聚合物的设计与合成

以甲基丙烯酸2-羟乙酯与五氧化二磷（P2O5）为原料，制备了丙烯酸-磷基单体双[2-（甲基丙烯氧基）乙基]磷酸（BMEP）。通过1H NMR， 31P NMR， MS和FTIR分析对BMEP的化学结构进行了鉴定。随后，脂肪族聚氨酯丙烯酸酯低聚物（AUA）与甲基丙烯酸异戊酯（IPEMA）反应，生成一种新型聚合物（UAIPA）。该聚合物通过加入浓度为2%、4%和6%的BMEP进一步改性，得到含磷聚合物。用FTIR， XRD， SEM， DSC， TGA和EDS对这些聚合物进行了表征。它们具有优异的缓蚀性能，缓蚀效率约为99%。此外，对含磷聚合物在金属表面的粘附性能进行了评估，得出5B级。高附着力支持了它们作为有效防腐涂料的潜力。综上所述，新型磷功能化丙烯酸酯聚合物具有优异的多功能特性，非常适合于先进的涂层应用，并为材料科学和聚合物化学开辟了新的可能性。
