2propenowym

2-propenoyl, also known as acryloyl, is a functional group characterized by a vinyl group attached to a carbonyl group. Its chemical formula is CH2=CHCO-. It is derived from acrylic acid. The double bond in the vinyl group makes it highly reactive, particularly in polymerization reactions. This reactivity is the basis for its widespread use in the production of polymers and copolymers.

Polymers derived from 2-propenoyl groups, such as polyacryloyl derivatives, exhibit a range of useful properties. These properties can be tailored by the specific monomers copolymerized with it. For instance, polyacrylamide, a polymer formed from acrylamide (which contains the 2-propenoyl group), is known for its ability to absorb large amounts of water and is used in applications like superabsorbent polymers, flocculants in water treatment, and in various biotechnological processes.

Esters and amides of acrylic acid are common compounds containing the 2-propenoyl moiety. These can be polymerized through free radical polymerization, anionic polymerization, or other mechanisms. The presence of the electron-withdrawing carbonyl group adjacent to the double bond influences the reactivity of the double bond, making it susceptible to nucleophilic attack and participating in Michael additions. Due to its versatile reactivity and the desirable properties of its resulting polymers, the 2-propenoyl group is a fundamental building block in polymer chemistry and finds application in a vast array of industrial and consumer products.
