Vinyl carbamate is a carbamate ester. Like amides they form polymers such as polyurethane resins. Due credit and reputation for authors. Cholinesterase inhibition is more transient than with organophosphates so clinical course tends to be more benign.

Karbamat carbamate ion ag l 17931 chebi. A carbamate is a chemical compound that is formally derived from carbamic acid nh 2 cooh. Polyurethane polymers are traditionally and most commonly formed by reacting a di or triisocyanate with a polyol since polyurethanes contain two types of. Polyurethane pur and pu is a polymer composed of organic units joined by carbamate urethane links.

Acetylcholinesterase inhibition excess accumulation of acetylcholine at the neuromuscular junction and cholinergic toxicity. Polymers whose units are joined by divalent. Imagine a global collaborative knowledge base for original thoughts. Search thousands of articles and collaborate with scientists around the globe.

As well as salts with the carbamate anion h 2 ncoo e g. An industrially important example is vinyl chloride precursor to pvc a plastic. In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom. The world s first wiki where authorship really matters nature genetics 2008.

Urea also known as carbamide is an organic compound with chemical formula co nh 2 2 this amide has two nh 2 groups joined by a carbonyl c o functional group. Carbamates are incompatible with strong acids and bases and especially incompatible with strong reducing agents such as hydrides. Carbamates are chemically similar to but more reactive than amides. Despite its name it is not a component of polyurethanes because it is a carcinogen it is little used but it naturally forms in low quantities in many types of fermented foods and drinks.

The term includes organic compounds e g the ester ethyl carbamate formally obtained by replacing one or more of the hydrogen atoms by other organic functional groups. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. While most polyurethanes are thermosetting polymers that do not melt when heated thermoplastic polyurethanes are also available.
