MMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications. [15]
PMAA can act as a polyelectrolyte and has the ability to absorb and retain water. These properties are strongly affected by the pH and therefore many hydrogels are composed of PMAA copolymers. [ 3 ] [ 4 ] These hydrogel capsules can act as carrier vessels for confined drugs and act as microreactor reservoirs. [ 5 ]
The final product is a dispersion of polymer particles in water. It can also be known as a polymer colloid, a latex, or commonly and inaccurately as an 'emulsion'. Smith-Ewart theory does not predict the specific polymerization behavior when the monomer is somewhat water-soluble, like methyl methacrylate or vinyl acetate.

This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step. Another route to methacrylic acid starts with isobutylene, which obtainable by dehydration of tert-butanol. Isobutylene is oxidized sequentially to methacrolein and then methacrylic acid.
Acetone cyanohydrin is an intermediate en route to methyl methacrylate. [6] Treatment with sulfuric acid gives the sulfate ester of the methacrylamide, [clarification needed] methanolysis of which gives ammonium bisulfate and methyl methacrylate. [7] It is used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium ...
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 ).
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 ...
