The United States has developed new biodegradable polymers

our most common polymer is plastic, and research shows that it is very unlikely to return these used plastics to their original state and produce new products. American researchers use monomers γ- Butyrolactone (GBL) has developed a new biodegradable polymer. This monomer is too stable to be used in making plastics, but researchers have made a breakthrough this time

researchers from Colorado State University used monomers γ- Butyrolactone (GBL) is a new biodegradable polymer. This new type of plastic is transformed back to its original molecular state when heated. This new type of plastic will change the way people use plastic. It can be completely recycled, reused, biodegradable and free of any petroleum components

people found this monomer GBL (butyrolactone) in cleaning solution and super glue. Because its structure is too stable, it is difficult to be used to make plastics, but this time researchers made a breakthrough. Previous studies have shown that monomer GBL cannot be converted into polymer based on measured reaction thermodynamic data. Chen Youren, a chemistry professor, and his team questioned the previous report and tried to aggravate the monomer GBL into a polymer, which produced a breakthrough

the new polymer obtained is called poly (GBL). When it is heated at ℃ or ℃ for 60 minutes, the polymer will change back to monomer GBL. Professor Chen and his team are determined to manufacture degradable polymers and plastics to replace the current petroleum based plastics

the most common artificial polymer is plastic. Synthetic polymers such as polystyrene and polyethylene are largely treated through landfills and oceans. Technically speaking, these plastic packages and bottles marked with "recyclable" are only a certain degree of reuse. However, the dynamometer is also classified according to the largest force value applicable to the structure and samples of a universal testing machine. It is impossible for these used plastics to return to their original state and produce new products

1. The State Council No. 46 civilization confirmed the high-pressure warning line of the utilization range of the combustion performance of thermal insulation materials. "Now the latest trend is to produce bio renewable and biodegradable polymers and plastics. However, in terms of raw material recycling, this is only a part of the solution, because biodegradable polymers do not need to be recycled." Professor Chen said so

we manufacture more than 2.7 million tons of plastic products every year, of which about 180000 tons eventually return to the ocean. It is estimated that each person in the world consumes about 200 pounds of plastic products made of artificial polymers every year

"in my 15 years at Colorado State University, this is the most exciting work my team has done." Professor Chen is also the winner of the U.S. president's Green Chemistry Challenge Award

Scott Grayson, a chemist at Tulane University who was not involved in this study, praised Professor Chen's research and described Professor Chen's findings as "a good step in the right direction." Grayson likens the discovery of biodegradable, bioavailable and recycled polymers in this field to the discovery of the Holy Grail
