| 摘 要： | 考察了聚甲醛(POM)与热塑性酚醛树脂(Novolak)的相容性;浊点法研究结果表明,POM/Novolak共混物存在一个低位临界相转变温度.DSC测试表明,POM与Novolak共混后,共混物的熔点下降;通过DSC测试得到数据,采用Hoffman-Weeks平衡熔点外推法和Flory熔点下降方程推算出POM与Novolak的相互作用参数(χ)约为-0.032.FTIR研究表明,Novolak的羟基能够与POM的醚氧基形成氢键,导致共混物中Novolak的羟基峰向高频偏移.研究结果表明,POM与Novolak能够达到热力学相容.

| Abstract: | The miscibility of polyacetal(POM) with Novolak was studied. It was found that POM/Novolak blends showed a lower critical solution temperature in their cloud point curve and the melting point decreasing by DSC test. The interaction parameter(χ) of POM and Novolak was calculated by Hoffman-Weeks' equilibrium melting point method and Flory equation. The investigation of FTIR for POM/Novolak blends demonstrated that there was a hydrogen bond between the molecular chain of POM and Novolak, which resulted in the movement of absorption peak to a low frequency. All results certified that POM was miscible with Novolak. |
