Problems solved by technology

For example, polylactic acid obtained from plant materials has attracted everyone's attention, but compared with the original petroleum-based plastics, this polylactic acid plastic has poor mechanical strength, heat resistance, hydrolysis resistance and many other properties, making it used in packaging materials. , food container materials, etc. are restricted
[0004] There are also bibliographic reports on the production of polyester from furan dicarboxylic acid of biological origin. For example, Japanese Patent Laid-Open No. 2007-146153 discloses a polymer compound containing a furan ring structure, but the polyester provided here has low molecular weight and poor mechanical properties. Good, poor heat resistance, so it is greatly limited in practical aspects

Abstract

The invention discloses a macromolecular polymer and a preparation method thereof. The macromolecular mainly contains a copolymer X of furandicarboxylic acid and diol, and also contains a compound Y derived from titanium compounds, a compound X derived from phosphorus compounds and the like. The macromolecular polymer is obtained by esterification and polycondensation carried out under the catalytic action of the titanium compound and the like, with the furandicarboxylic acid and diol, which can be derived from a biological source, serving as starting materials. The macromolecular polymer can be made of raw materials which can be derived from a biological source, and has a higher melting point, high mechanical performance and high hydrolysis resistance.

Description

Technical field: [0001] The invention relates to a high molecular polymer and a production method thereof. Background technique: [0002] Polyester obtained by copolymerization of aromatic dibasic acid and aliphatic diol, its product has good heat resistance and mechanical properties, so it is widely used in resin, fiber, film and other fields. [0003] In recent years, due to the lack of petroleum resources and the emphasis on environmental protection, people have paid more and more attention to the use of bio-sourced raw materials to develop new polymers to produce environmentally friendly polymer products. For example, polylactic acid obtained from plant raw materials has attracted much attention. However, compared with the original petroleum raw material plastics, this polylactic acid plastic has poor mechanical strength, heat resistance, hydrolysis resistance and other properties, which makes it suitable for packaging materials. , Food container materials, etc. are restricted...
