Мetilmetakrilat 

Methyl methacrylate (MMA) is a colorless, transparent liquid with a pungent unpleasant odor. MMA is characterized by reactions at the double bond and reactions at the ester group. For example, it is hydrolyzed in the presence of mineral acids or alkalis to methacrylic acid; it can also be subject to ammonolysis or transesterification when interacting with ammonia or alcohol. Easily polymerized and copolymerized under free radical or anionic polymerization conditions. Polymerization proceeds with the release of heat and, in case of uncontrolled conduct, self-heating of the mixture may occur. An explosive course of the reaction is not excluded.

Methyl methacrylate is used:

— to obtain polymethyl methacrylate (PMMA) - organic glass;
— as a comonomer in the production of double, ternary and other copolymers with butadiene, styrene;
— as a raw material for the preparation of acrylic acid esters with higher alcohols.
