阅读说明：本技术 聚酯和多糖的共混物 (Blends of polyesters and polysaccharides ) 是由 R·S·约翰逊 V·米什拉 于 2019-02-07 设计创作，主要内容包括：一种聚酯组合物,其包含至少一种聚酯,所述聚酯选自由以下组成的组：聚(对苯二甲酸三亚甲酯)、聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、及其共聚物；以及至少一种聚α-1,3-葡聚糖酯,所述聚α-1,3-葡聚糖酯的聚α-1,3-葡聚糖重复单元具有约0.3至3摩尔的至少一种酰基的取代度。由这些聚酯组合物制备的制品展现出至少一种改善的物理特性,如热挠曲温度、拉伸强度、杨氏模量或冲击强度。此类聚酯组合物还可以由可再生资源制备。(A polyester composition comprising at least one polyester selected from the group consisting of: poly (trimethylene terephthalate), polyethylene terephthalate, polybutylene terephthalate, and copolymers thereof; and at least one poly alpha-1, 3-glucan ester having poly alpha-1, 3-glucan repeating units having a degree of substitution of about 0.3 to 3 moles of the at least one acyl group. Articles prepared from these polyester compositions exhibit at least one improved physical property, such as heat deflection temperature, tensile strength, young's modulus, or impact strength. Such polyester compositions can also be prepared from renewable resources.)
