Renewable resource derived polymers are the most widely explored polymers from the past two decades because of their non-toxicity and environment-friendly nature. Therefore, in the present study blends from two different bio-based polymers with the special architecture, viz. hyperbranched epoxy and hyperbranched polyester were prepared by mechanical mixing at different weight ratios. The prepared blends were characterized by Fourier transform infrared spectroscopy and X-ray diffraction technique. The thermosets of these blends showed good tensile strength (14.9 MPa), elongation at break (274%), impact resistance (21.3 kJ/m²), scratch resistance (up to 6.5 kg) and thermal (Onset temperature: 224 °C) properties indicating improvements in flexibility and thermostability up to an appreciable extent. The blends also showed good biodegradability when exposed to gram positive and gram negative bacterial stains.

可再生资源衍生的聚合物由于其无毒且环境友好的性质，是过去二十年来开发最广泛的聚合物。因此，在本研究中，将两种不同的具有特殊结构的生物基聚合物共混而成。通过机械混合以不同的重量比制备超支化的环氧树脂和超支化的聚酯。所制备的共混物通过傅里叶变换红外光谱和X射线衍射技术进行表征。这些共混物的热固性材料表现出良好的拉伸强度（14.9 MPa），断裂伸长率（274％），耐冲击性（21.3 kJ / m ^2）），耐刮擦性（最高6.5 kg）和热（起始温度：224°C）性能表明其柔韧性和热稳定性均得到了很大程度的改善。当暴露于革兰氏阳性和革兰氏阴性细菌污渍时，混合物还显示出良好的生物降解性。
