Problems solved by technology

Moreover, compared with the original petroleum-derived plastics, polylactic acid has poor mechanical strength, heat resistance, etc., which makes it limited in packaging materials, food container materials, etc.
[0003] On the other hand, currently, aromatic resins such as PET and PBT, which have excellent heat resistance and mechanical properties, are widely used in films, food containers, electronic products, automotive materials, etc., but PET, PBT, etc. are made of Manufactured from petroleum sources, hardly biosourced
[0004] There are also literature reports on polyesters produced from furandicarboxylic acid that can be produced from biological sources as raw materials, but these polyesters previously provided have low molecular weight, poor mechanical properties, and poor crystallization properties, so they are greatly limited in practical use.

Description

technical field [0001] The invention relates to a polymer compound and a production method thereof. Background technique [0002] In recent years, resins developed as environmentally friendly materials and renewable materials and resins developed from biological sources have been used in large quantities. However, these resins have many disadvantages compared with the plastics used in large quantities in terms of manufacturing price, mechanical properties, and heat resistance, and their hydrolysis resistance and light resistance are poor, so they cannot be used for a long time. For example, polylactic acid has attracted much attention because it is obtained from plants as raw materials, but the raw material of polylactic acid is obtained by fermentation of starch such as corn and wheat. Moreover, compared with the original petroleum-derived plastics, polylactic acid has poor mechanical strength, heat resistance and many other properties, which makes it limited in terms of p...
