Abstract
Poly[(3-hydroxybutyrate)-co -(4-hydroxybutyrate)] (P34HB), poly[(butylene succinate)-co -(butylene furandicarboxylate)] (PBSF) and poly(vinyl acetate) (PVAc) were melt-blended to prepare P34HB/PBSF/PVAc blends with improved ductility. The thermal properties, mechanical properties, rheological properties and morphology of the blends were systematically studied. The addition of PBSF promoted the melt crystallization of P34HB. The temperatures at 5% weight loss of the blends were higher than that of P34HB. The surface of the blends was investigated using scanning electron microscopy. The surface of P34HB was very smooth, but the surfaces of the blends were rough. PVAc can increase the compatibility between P34HB and PBSF. Compared with P34HB, the elongation at break of the blends was increased to 219.1%. © 2024 Society of Industrial Chemistry.
基于生物质的延展性聚[(3-羟基丁酸)-共(4-羟基丁酸)]混合物
将聚[(3-羟基丁酸)-共(4-羟基丁酸)]（P34HB）、聚[(丁二酸丁二醇酯)-共(呋喃二甲酸丁二醇酯)]（PBSF）和聚（醋酸乙烯酯）（PVAc）熔融共混，制备出延展性更好的 P34HB/PBSF/PVAc 共混物。对共混物的热性能、机械性能、流变性能和形态进行了系统研究。PBSF 的加入促进了 P34HB 的熔融结晶。混合物失重 5%时的温度高于 P34HB。使用扫描电子显微镜对混合物的表面进行了研究。P34HB 的表面非常光滑，但混合物的表面却很粗糙。PVAc 可以提高 P34HB 与 PBSF 的相容性。与 P34HB 相比，混合物的断裂伸长率提高了 219.1%。© 2024 工业化学学会。
