Changchun Institute of Applied Chemistry, Chinese Academy of Sciences recently heard the good news, the last 8 years by research and cooperation with enterprises to break through the carbon dioxide to biodegradable plastic (PPC) Research on key technology of the series and set the field of research the world?s first seven .
7 the results of this study are as follows: in Inner Mongolia into the world?s first and largest of 3000 tons / year production line PPC; first polymer of carbon dioxide in the world will be the glass transition temperature to -10 ¡æ ~ 120 ¡æ, the use of temperature raised to 70 ¡æ, significantly expanding the scope of application of the PPC; pioneered the development of a number of more than 150,000 average molecular weight, weight-average molecular weight of more than one million, carbon dioxide content of more than 42% (mass ratio) copolymer of carbon dioxide; the first time can be produced with completely biodegradable material properties of high-barrier film, the film can be used in food packaging materials of mass; the first breakthrough in the international carbon dioxide copolymer film for blowing into the processing bottlenecks, developed with independent intellectual property rights of China?s large-scale, continuous Preparation of thin-film technology; successfully developed PPC medical dressings, the dressing of the establishment of enterprise standards, access to the world?s first one-time carbon dioxide medical copolymer degradable material production license.
Carbon dioxide copolymer (PPC) is based on carbon dioxide as the main raw material, after polymerization of green synthetic polymer materials, this new type of biological material can be carbon dioxide waste into useful, but also completely biodegradable, is to save the oil resources the importance of the sustainable development of biological materials green.
