After four years of hard development, the project has achieved three world firsts: Solved the cold flow problem of carbon dioxide copolymer for the first time in the world ； The first to develop high-barrier film materials with biodegradable properties ； Obtained the world's first production license for carbon dioxide copolymer medical degradable materials. Since its inception, carbon dioxide copolymers have attracted much attention for their ability to efficiently utilize carbon dioxide and solve the 'white pollution' problem of plastics. However, problems such as low catalyst efficiency, poor polymer processability, and high cost that have always existed in the synthesis process have become bottlenecks for carbon dioxide copolymers and their industrialization, and are also the focus of competition among various countries. Changchun Institute of Applied Chemistry successfully developed a rare earth three-way catalyst that can be used industrially in early 2004, and built the world's first kiloton carbon dioxide copolymer production line in western Inner Mongolia, establishing my country's international leadership in this field. In order to accelerate the industrialization of carbon dioxide copolymers and develop carbon dioxide copolymer products with practical value, in October 2004, Changchun Chemical Industry Institute undertook and implemented a major project of the Jilin Provincial Science and Technology Development Plan - the industrialization promotion project of carbon dioxide copolymers and their products. The project lasted for four years and achieved a series of internationally leading innovative results. The new multi-element copolymer rare earth catalyst and new technology to strengthen cross-linking developed by the project team have solved the internationally unsolved problem of severe cold flow phenomenon in carbon dioxide copolymers above 30°C, and effectively improved the catalyst efficiency of carbon dioxide copolymers. The researchers introduced the method of external crystallization to control the polymer aggregation state, breaking through the technical problem of continuous blowing of carbon dioxide copolymer into films, and became the first in the world to develop a high-barrier film material with biodegradable properties. They also joined forces with Jilin Jinyuan North Technology Development Co., Ltd. to develop a carbon dioxide copolymer medical dressing, and obtained the world's first carbon dioxide copolymer medical disposable degradable material production license. At present, the company has invested 30 million yuan to establish a medical dressing production line. In addition, the project team also cooperated with China National Offshore Oil Corporation to successfully build a carbon dioxide copolymer production line with an annual output of 3,000 tons. At present, the Changchun Institute of Applied Chemistry and other units are jointly responsible for * * 'The 11th Five-Year Science and Technology Support Plan project - the research and development of key technologies for the industrialization of fully biodegradable plastics has also been launched. This project will build a number of 10,000-ton carbon dioxide copolymer production lines in the country and develop a series of low-cost, high-performance carbon dioxide copolymer products. .Note$#, $ $
