What is a plexiglas monomer?
Methyl Methacrylate
1 What are the purpose for washing monomer methyl methacrylate with sodium hydroxide and then followed by sodium chloride?
To remove the inhibitors present in the monomer to increase its shelf life. Washing of mma is required prior to polymerization
How do you separate mono-methyl hydroquinone ether from methyl methacrylate?
Monomeric methyl methacrylate can be freed of hydroquinone inhibitor by shaking with 5 N sodium hydroxide and desiccating with 8-mesh calcium chloride.
Where is acrylic obtained from?
You first produce methacrylic acid. Once you're there, you esterify it to methyl methacrylate monomer. Polymerizing the monomer produces polymethyl methacrylate, which is the chemical name of acrylic plastic. Over 8 billion kilograms of acrylic were sold in 2015, so there are a lot of companies making it and quite a few different processes.
What is the structural formula of methyl methacrylate?
H2C=C(CH3)COOCH3
What is the other name for perspex?
The plastic in perspex (the common US name is plexiglas) is poly(methyl methacrylate).
Is methyl methacrylate used in nail polish?
According to Sheldon Cooper - yes, and he can smell it.
What is the difference between acrylic and polymethyl methacrylate?
Poly(methyl methacrylate) or PMMA is commonly reffered to as acrylic or acrylic glass. So generally, they're the same thing.
What has the author Roy Ensor written?
Roy Ensor has written: 'Radical reactivities in the telomerisation of methyl methacrylate'
The monomer unit of perspex is?
Perspex is polymethylmetacrylate. Epoxy is polyepoxyde.
What has the author John Frederick Norris written?
John Frederick Norris has written: 'A study of the polymerization and copolymerization of methyl methacrylate'
What is hard monomers and soft monomers?
The monomer can be categorized into three classes. The first two classes are characterized by their respective Tg values. Soft monomers, characterized by low Tg values, include n-butyl acrylate, 2-ethyl hexyl acrylate and iso-octyl acrylate. These monomers are longer chain alkyl acrylates and exhibit low water solubility (i.e., high hydrophobicity). Hard monomers, characterized by high Tg values, include styrene, methyl methacrylate, ethyl acrylate and methyl acrylate. The third class is the functional monomer with various functional groups, such as carboxyl or hydroxyl. Examples of functional monomers are acrylic acid and hydroxyethyl acrylate,which are very water-soluble. The hydrophobicity of the hard monomer depends on the monomer structure. Methyl acrylate and ethyl acrylate, which are short-chain alkyl acrylates, have higher water solubility.
