Introduction: PCHC is an important aliphatic polycarbonate, which is not only biodegradable, but also has excellent oxygen and water barrier properties.
It can be used as engineering plastics, disposable medicine and food packaging materials.
It is a green chemical product, and compared with the degradable material polymethyl ethylene carbonate (PPC), PCHC has a higher glass transition temperature (about 120 ° C) due to the insertion of a rigid group cyclohexyl on the main chain of PCHC.
, which helps to improve the problem of poor temperature resistance of PPC, so PCHC is expected to become the most important carbon dioxide-based polymer after PPC

Project meaning
project meaning project meaningThis project uses the greenhouse gas carbon dioxide as the raw material, and the carbon sequestration rate is as high as 31%.
After the successful pilot test of the project, the process technology can make the coal chemical enterprises and thermal power enterprises affiliated to Shaanxi Coal Group emit waste gas in the operation process when the industrialization device is constructed.
The realization of resource utilization of CO 2 is conducive to the solid promotion of carbon peaking and carbon neutrality of Shaanxi Coal Group, which is conducive to better coping with climate change, promoting green and low-carbon development, and promoting the diversification of carbon emission reduction implementation paths.
Development is in line with the requirements of the Party Central Committee to achieve carbon peaking and carbon neutrality
.The pilot product PCHC of this project is biodegradable and is a degradable material.
At the same time, PCHC has excellent comprehensive properties and can become an ideal substitute for the currently widely used non-degradable plastics, fundamentally solve the problem of "white pollution", and help plastics The pollution control goals were achieved on schedule
.This project can effectively alleviate the dependence of the polymer material industry on petroleum and other fossil resources, realize the diversification of raw material sources for the polymer material industry, and at the same time realize the artificial carbon cycle and promote high-quality economic development
The implementation of this project can effectively promote the technological progress of the new material industry, make up for the shortcomings of the industrial chain, and promote the extension of the new material industry to high value-added industries
