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.
PMMA vaporizes to gaseous compounds (including its monomers) upon laser cutting, so a very clean cut is made, and cutting is performed very easily. However, the pulsed lasercutting introduces high internal stresses, which on exposure to solvents produce undesirable "stress- crazing " at the cut edge and several millimetres deep.
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.
Clone Hero started as a small project of Ryan Foster's in 2011, [2] then called GuitaRPG, built in the XNA engine and bearing simple, 2D graphics. [10] Around 2015, the game's name was changed to Guitar Game to reflect its forking away from the RPG style, and had been upgraded with pseudo-3D graphics made with 2D graphics with warped perspective.

10-Methacryloyloxydecyl dihydrogen phosphate (10-MDP, MDP Monomer) is a chemical compound used in dental adhesive materials. This organophosphate monomer was developed in 1981 by the Japanese company Kuraray for the preparation of dental adhesion polymers [ 1 ]

This is referred to as air inhibition and is a diffusion-controlled reaction with rates typically in the order of 10 7 –10 9 mol −1 s −1, [3] the resulting peroxy radicals (ROO•) are less reactive towards polymerisation. However air stabilisation is not suitable for monomers with which it can form explosive peroxides, such as vinyl ...
Epoxide monomers may be cross linked with themselves, or with the addition of a co-reactant, to form epoxy; BPA is the monomer precursor for polycarbonate; Terephthalic acid is a comonomer that, with ethylene glycol, forms polyethylene terephthalate. Dimethylsilicon dichloride is a monomer that, upon hydrolysis, gives polydimethylsiloxane.
