Bio-based Polyester And Polycarbonate Projects Will Soon Be Included In The National Key Special Plan!

On December 13, 2021, in accordance with the "Several Opinions of the State Council on Improving and Strengthening the Management of Central Fiscal Research Projects and Funds" (Guo Fa [2014] No. 11), "The State Council on Deepening the Management Reform of Central Fiscal Technology Plans (Special Projects, Funds, etc.) The “Notice of the Plan” (Guo Fa [2014] No. 64) and the “Notice of the Ministry of Finance on Printing and Distributing the Measures for the Administration of Funds for National Key R&D Programs” (Cai Jiao [2021] No. 178) and other document requirements are now The information of the key special project of "Structure and Composite Materials" to be established in 2021 will be publicized.

Among them, the "Preparation and Industrialization of Low Cost and High Performance BIO-based Polyester and Polycarbonate" project was led by Zhu Jin's team from Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences. The publicity time is from December 13, 2021 to December 17, 2021.

On February 1, 2021, the Ministry of Science and Technology issued a notice for soliciting opinions on the 2021 project application guidelines for 18 key special projects of the "14th Five-Year" national key research and development plan. Among them, the preparation and industrialization of low-cost bio-based engineering plastics, the development of key technologies for flame-retardant Polymer materials for high-end applications, and the repeated chemical cycle biodegradable polymer materials were selected as "Advanced Structures and Composite Materials", "High-end Functionality and "Intelligent Materials" key special project. details as follows:

Preparation and industrialization of low-cost bio-based engineering plastics (common key technologies)

Research content: Facing the problems of high cost of bio-based polymer materials and low grades of high-performance engineering plastics, focus on the development of low-cost bio-based furandicarboxylic acid (FDCA) and isosorbide preparation technology; development of 1,4-cyclohexane The domestic production technology of dimethanol (CHDM) is based on the development of three types of high-performance polyesters of bio-based polyesters PEF, PCF and PETG based on new monomers, and the entire chain is studied from monomers and polymers to back-end applications. Fine-tune the product structure, study the temperature resistance, mechanical properties, and barrier properties of the product, develop no less than 10 high-performance polyester products, and apply them downstream.

Assessment indicators: the product purity of furandicarboxylic acid is ≥99.5%, the cost of ton-level is less than 20,000 yuan, and the thousand-ton-level pilot test demonstration is completed; the purity of CHDM is ≥99.9%; the mechanical strength of PEF is ≥75MPa, and the glass transition temperature is ≥80℃ , Establish a 10,000-ton industrial production line. Based on CHDM to develop low-cost PCF, PETG, and bio-based polyester with furandicarboxylic acid, the product cost is less than 20,000 CNY/ton, the tensile strength is ≥80MPa, and the tensile modulus is ≥2.5GPa. Develop new products of no less than 6 grades and realize the stable production of polyester at the 1,000-ton level.

On May 13, 2021, the Ministry of Science and Technology issued the 2021 project application guidelines for the key special projects of the national key research and development plan "Advanced Structures and Composite Materials".

The guideline is clear: The 2021 guideline deployment adheres to the principles of problem-oriented, step-by-step implementation, and focused attention, focusing on high-performance polymer materials and their composite materials, high-temperature and special metal structural materials, light-weight and high-strength metals and their composite materials, and advanced structures. Ceramics and ceramic matrix composite materials, advanced engineering structural materials, new technologies for preparation, processing and evaluation of structural materials, and structures and composite materials based on genetic engineering of materials. According to the three levels of "basic frontier technology, common key technology, and demonstration application", 37 projects are planned to be launched, and 632 million yuan is planned to be allocated from the state. Among them, 9 young scientist projects are planned to be deployed, and 36 million yuan will be allocated from the state, 4 million yuan for each project. Among them, the preparation and industrialization of low-cost bio-based engineering plastics

Facing the problems of high cost of bio-based polymer materials and few high-performance engineering plastics, we focused on the development of low-cost bio-based furandicarboxylic acid (FDCA) and isosorbide preparation technology; developed 1,4-cyclohexanedimethanol ( CHDM) and 2,2,4,4-tetramethylcyclobutanediol (CBDO) domestic production technology, based on bio-based monomers and new monomers to develop bio-based polyesters such as PEF, PCF, PIF and PETG, and Bio-based polycarbonate such as PIC and PCIC, from monomer, polymer to back-end application full chain research. Finely control the product structure, study the temperature resistance, mechanical properties, and barrier properties of the product, develop no less than 8 high-performance polyester and polycarbonate products, and apply them in the packaging field.
