| 摘 要： | 采用SEM、FT-IR、DSC、WAXD等方法对POM/PA12共混物的微观结构进行分析,并测试其力学性能,结果表明,在POM/PA12共混物中,存在着氢键的相互作用.PA12的加入,使POM的熔点下降,共混物的微晶尺寸入L110及晶胞参数有所增大.微晶尺寸L110在10.8714.89nm之间时,PA12对POM具有增韧改性作用.

| Abstract: | The Microstructures of polyoxymethylene/polyamide 12 blends(POM/PA12)were analyzed by SEM,FT-IR,DSC and WAXD techniques and mechanical property mea-surement.The results showed the existence of hydrogen bonds in the blends. Addition ofPA12 caused the decrease of T_m of POM and increases of the crystallite size L_110 and the cellparameters of the blend.Crystallite size L_110 between 10.87nm and 14.89nm led to an in-creased thoughness of the blends. |
