Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.
Methacrylates ( CH 2 =C(CH 3)CO 2 R) and cyanoacrylates ( CH 2 =C(CN)CO 2 R,) are closely related to acrylates. The feature a methyl and a nitrile in place of the H alpha to the carboxy functional group. They share several properties, being polymerized by radicals and being colorless.

α,β-Unsaturated carbonyl compounds featuring a carbonyl conjugated to an alkene that is terminal, or vinylic, contain the acryloyl group (H 2 C=CH−C(=O)−); it is the acyl group derived from acrylic acid. The preferred IUPAC name for the group is prop-2-enoyl, and it is also known as acrylyl or simply (and incorrectly) as acryl. Compounds ...
CH 2 =C(CH 3)CN + H 2 SO 4 + H 2 O → CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 + CH 3 OH → CH 2 =C(CH 3)COOCH 3 + NH 4 HSO 4. Mitsubishi Gas Chemicals proposed that MAN can be hydrated to methacrylamide without using sulfuric acid and is then esterified to obtain MMA by methylformate. [10] CH 2 =C(CH 3)CN + H 2 O ...
An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
Poly(methyl acrylate) (PMA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 3) n. It is a synthetic acrylate polymer derived from methyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers.
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic , used as an engineering plastic . PMMA is also known as acrylic , acrylic glass , as well as by the trade names and brands Crylux , Hesalite , Plexiglas , Acrylite , Lucite , and Perspex , among several others ( see below ).
