摘要:

采用熔融聚合法, 以间苯二酚、 三氯氧磷和苯酚为原料, 通过两步合成, 制备了阻燃剂聚苯基磷酸间苯二酚酯(PRPP). 用红外光谱(FTIR)、 1H, 13C和31P核磁共振(NMR)、 凝胶色谱(GPC)及热重分析(TGA)等对聚合物的结构、 分子量、 热性能进行了表征. 结果表明, PRPP具有与液态商品间苯二酚双(二苯基)磷酸酯(RDP)相同的组成单元, 其数均分子量为3227, 分子量分布系数Mw/Mn=1.31, 聚合度n≈12; PRPP的起始分解温度与液态RDP相同, 但在高温下PRPP的热稳定性优于RDP, 其分解50%质量的温度提高了235 ℃, 在高温阶段表现出优良的成炭性能.

Abstract:

Poly(resorcine phenyl phosphate)(PRPP) was synthesized with melting polymerization by resorcine, phosphorus oxychloride and phenol. The structure of PRPP was characterized by FTIR, 1H, 13C and 31P NMR. Thermal property of PRPP was investigated by thermo gravimetric analyzer(TGA). The result shows that PRPP is composed by the same structure as commercial RDP flame retardant. The initial decomposition temperature of PRPP is same as RDP's. PRPP shows good thermal stability than RDP at higher tempe-rature and excellent charing property by giving a 46.64% char yield at 700 ℃.

Key words: Poly(resorcine phenyl phosphate), Flame retardant, Melting polymerization
