Carbon dioxide is a lot of resources to be able to get cheap , although researchers have previously synthesized carbon dioxide as a raw material of plastic , but the proportion of low carbon dioxide content ruthless , these plastics when burned, produces toxic nitrogen oxide gases , and its resistance to heat is not strong , the hardness of hard big change occurs at near ambient conditions.Masking tape
Kyoko Nozaki and colleagues at Tokyo University professor in the new issue of the British journal "Nature Chemistry" online edition reported that they would dioxide and synthetic rubber as a raw material for mass production of butadiene together using a palladium catalyst and radical polymerization reaction , creating a new type of plastic .Washi tape
The plastic in powder form , may extend into the molten transparent sheet material , even if the combustion does not produce nitrogen oxides. The proportion of the plastic content of up to 29% carbon dioxide , even at high temperatures it is hardly deformed , up to the decomposition temperature 340 degrees Celsius, the melt can be injection molded .
The research team believes that this new type of plastic due to the high hardness , it is widely used, can be used in the manufacture of plastic containers, films and so on. In the future by expanding production and improving production technology, is expected to produce this cheap plastic , there may utilize the carbon dioxide produced by coal-fired power stations and other manufacturing such products , to reduce greenhouse gas emissions to make some contribution .Sellotape
