摘要:
#$%^&*AU2009332928B220130509.pdf#####ABSTRACT OF THE DISCLOSURE The present invention relates to a kind of biodegradable polyester and its preparation method, which belongs to the field of biodegradable co-polyester product technology. The number-average molecular weight of the biodegradable 5 polyester material under this invention is 6000-135000g/mol, the molecular weight distribution is 1.2-6.5, and the range of crystallization temperature is 15'C-105'C, which could overcome the disadvantages of existing technical products and can be processed into membrane materials, sheet materials and foam materials. During processing, the picking property will be dramatically changed with the appearance 10 quality improved; after heat resistance is improved, this new type of polyester material could also be applied to the processing course with long cycles, for example, the injection processing course, and the biodegradable aliphatic/aromatic polyester materials provided by this invention has excellent mechanical properties.
