Morphology and thermal property of PP/ M-PEEAM composite
Zinc oxide, hexanedioic acid, PEG ，caprolactam and MDI were chosen as raw materials to synthesize poly(ether ester amide containing zinc) (M-PEEAM). The PP/M-PEEAM composite and fiber were then prepared by blending M-PEEAM and PP. The rheological and thermal properties of the PP/M-PEEAM composite were investigated, and the microstructure of the PP/M-PEEAM fiber was observed by SEM. The rheological study indicated the complex viscosity of the PP/M-PEEAM composite reduced with the increase of the frequency within a certain range, which explains that the PP/M-PEEAM composite showed obviously rheological behavior of pseudoplastic fluid. DSC study indicated the composite had a large endothermic peak at 166-167 ℃ and two small endothermic peak at 50 ℃ and 218 ℃, respectively, implying that PP was incompatible with M-PEEAM. However, the M-PEEAM content in the composite had not much influence on the melting temperature of PP. SEM showed that PP/M-PEEAM blends gave a two-phase structure with spherically M-PEEAM dispersed in PP matrix and the size of dispersion phase increased with increasing M-PEEAM content.
