摘要：以甘油为增塑剂制备了热塑性淀粉（TPS）；利用自制的甘油基阴离子表面活性剂（2-十六烷基羧酸酯）丙二羧酸钠（C）为增容剂，制备了PP/TPS/C共混材料，并对其力学性能、熔点、结晶温度、热稳定性、流变性能等进行了分析。结果表明，在100份的PP/TPS（70:30）共混材料中加入2份C时，其力学性能和流变性能最好：拉伸强度由21.3 MPa降至17.8 MPa，断裂伸长率由9.3%升高至19.7%，提高了115%；流动性变好，表观黏度明显降低。由于增容剂是甘油基阴离子表面活性剂，其与增塑剂甘油、淀粉以及PP都能产生一定的相互作用，从而影响了共混材料的性能。

Abstract：Thermoplastic starch (TPS) was prepared using glycerol as a plasticizer, and PP/TPS/C blends were prepared using a self-made glycerol-based anionic surfactant, sodium (2-hexadecyl carboxylate) malonate (C), as a compatibilizer. The mechanical properties, melting point, crystallization temperature, thermal stability and rheological properties of the blends were analyzed. The results show that when 2 parts of C were added to 100 parts of PP/TPS (70:30) blend, the mechanical and rheological properties were the best: the tensile strength decreased from 21.3 MPa to 17.8 MPa, the elongation at break increased from 9.3% to 19.7%, an increase of 115%, and the fluidity improved with a significantly decreased apparent viscosity. Because the compatibilizer is a glycerol-based anionic surfactant, it can interact with the plasticizer glycerol, starch and PP, thereby affecting the properties of the blends.
