WebTo study the possibility of living cationic polymerization of vinyl ethers with a urethane group, 4-vinyloxybutyl n -butylcarbamate ( 1) and 4-vinyloxybutyl phenylcarbamate ( 2) … Ethyl carbamate (also called urethane) is an organic compound with the formula CH3CH2OC(O)NH2. It is an ester of carbamic acid and a white solid. Despite its name, it is not a component of polyurethanes. Because it is a carcinogen, it is rarely used, but naturally forms in low quantities in many types of fermented foods and drinks.
