Can carbon dioxide polymerize?

In fact, carbon dioxide can not only polymerize, but finished products are already available for sale! You can first search online; I’m sure you’ll find a great deal of information on the polymerization of dioxide!

Do you mean carbonate? What I mean is simply aggregated carbon dioxide! Purely polymerized carbon dioxide without other epoxides or monomers such as bisphenol A – carbon dioxide that is polymerized in a crystal-like form of silica!

There are carbon dioxide polymers, which are said to be already on the market. The Guangzhou Institute of Chemistry, Chinese Academy of Sciences, is at the forefront in this area.

Replying to the person on the third floor: I was referring to carbon dioxide polymers; you can search on Baidu and find plenty of information on this topic. :L

You don’t know until you see it; it’s a shock when you do! Sure enough, there are carbon dioxide polymers; just search on Baidu and you’ll find a lot of information on this topic!

It’s my first time encountering carbon dioxide polymers too; it’s really informative~~~

These are the results I found on Baidu. I just registered; I’m not very wealthy, so I post more content and try to get sponsorships :lol http://zhidao.baidu.com/question/44056481.html?si=1 Carbon dioxide polymer is a new type of synthetic material under research. Using carbon dioxide as the monomer, and with the help of bimetallic coordination PBM-type catalysts, it is activated to a high degree and then copolymerized with epoxides to produce aliphatic polycarbonates (PPC). After further processing, carbon dioxide resin materials are obtained. By adding other reactants during polymerization, carbon dioxide resins with various chemical structures can be obtained. Carbon dioxide copolymers have flexible molecular chains, and their properties can be adjusted by altering their chemical structure ； It decomposes more easily under the action of heat, catalysts, or microorganisms, but can also be controlled through certain measures: it has very low permeability to oxygen and other gases. Products with the following applications can be developed: 1. Polyurethane materials prepared from aliphatic polycarbonates and polyisocyanates, which exhibit better hydrolysis resistance than conventional polyester polyurethanes. 2. Use maleic anhydride as the third monomer for terpolymerization ； The product is an unsaturated resin containing carbonate and ester groups; it can be cross-linked and cured, as well as compounded with solids such as fibers. It is a new material similar to conventional unsaturated polyesters. 3. Aliphatic polycarbonates can be blended with various polymers to obtain a range of different properties. It can be used as a toughening agent, plasticizer, or processing aid for epoxy resins, PVC plastics, etc. 4. Copolymers of carbon dioxide, ethylene oxide, etc., and terpolymers of carbon dioxide, propylene oxide, and succinic anhydride can be completely degraded by microorganisms without leaving residues, making them promising biodegradable materials. 5. Carbon dioxide copolymers have excellent biocompatibility. Specially designed copolymers are expected to be used as anticoagulant materials or as drug release agents. 6. Certain carbon dioxide copolymers can be used as surface treatment agents for solid pigments or fillers, oxygen-barrier materials, surfactants, ceramic adhesives, hot-melt adhesives, and more. 7. The polypropylene carbonate butyl rubber blend exhibits good resistance to oil, heat, and oxygen aging, as well as superior mechanical properties compared to conventional butyl rubber; it is an excellent new type of oil-resistant rubber. The cost of the resin per ton of carbon dioxide in this project is roughly equivalent to the price of propylene oxide as a raw material, which is 3-30% of the cost in foreign production methods; thus, it has great potential to establish itself and develop overseas. The cost of PPC/NBR type oil-resistant rubber can be reduced by about 10% compared to pure nitrile rubber, resulting in a cost savings of over 1,000 yuan per ton of product.

There are many. I also found a bunch of them

I’m not sure if you’re referring to polymers with a –C(O2)– structure; it’s not yet possible to obtain CO2 homopolymers, and is silica a spatially polymeric structure? Is it polysilane? Actually, it is not obtained through the polymerization of silica; what others have answered is that it is a carbon dioxide copolymer, and carbon monoxide can also be used in copolymerization.

So what are the temperature and pressure conditions under which carbon dioxide can be copolymerized? If such a method really worked well and could be put into industrial use, it would help solve the problem of plastic pollution as well as the greenhouse effect caused by carbon dioxide. There’s no news coverage either about such a great thing.

The answers don’t seem to be relevant to the question, do they? :)
