What is poly glycidyl methacrylate?
Glycidyl methacrylate, having both vinyl and epoxy functions, is a reactive monomer which meets the requirements for post-polymerization modification. It is also a low-cost reagent because it is widely used for the industrial production of epoxy functional methacrylic resins to be employed as coatings and adhesives.
What is glacial methacrylic acid?
Glacial Methacrylic Acid (GMAA) is an with the molecular formula C4H6O2, CAS 79-41-4. GMAA is a clear, colorless liquid at room temperature with a pungent, irritating odor. It is a versatile chemical which is used as an intermediate in the manufacture of methacrylic acid esters.
What is Glycidol used for?
Glycidol is used as a chemical intermediate in the pharmaceutical industry, as a stabilizer in the manufacture of vinyl polymers, and as an intermediate in the synthesis of glycerol, glycidyl ethers, and amines.
What is an epoxy group?
The term ‘epoxy’ refers to a chemical group consisting of an oxygen atom bonded to two carbon atoms that are already bonded in some way. The simplest epoxy is a three-member ring structure known by the term ‘alpha-epoxy’ or ‘1,2-epoxy’.
Is methacrylic acid water soluble?
Methacrylic acid, abbreviated MAA, is an organic compound. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents.
Is methacrylic acid hydrophilic?
Hydrophilic monomer methacrylic acid was copolymerized with hydrophobic monomer butylmethacrylate in different molar ratio, using AIBNfree radical initiator. Successful polymerization was confirmed by FTIR and 1H NMR, while DSC and XRD revealed the amorphous nature of the polymers.
What is glycidyl ester?
Glycidyl esters (GE) are process contaminants generated during the deodorisation step of edible oil refining. In particular, GE are found in high abundance in refined palm oil. In addition, isomers of GE, formed from DAG heated at T > 140 °C, were identified as oxopropyl esters.
What is glycidol made of?
Glycidol, also known as 2,3-epoxy-1-propanol, is derived from glycidyl esters (GEs) found in fats and oils. Upon intake of GEs through food consumption, it is broken down into glycidol in human digestion. The GEs contaminants are formed at high temperature (above 200°C) during the refining process of vegetable oils.
What is epoxy hardener made of?
Epoxy resins are thermosetting polymers with unique mechanical and resistance properties. They are the result of a chemical reaction called ‘curing’, which involves epoxides and other chemicals more commonly known as ‘hardeners’ or curing agents.
How strong is epoxy?
Let me clarify – single component epoxy adhesives have the highest tensile strength often 35-41 N/mm² (5100– 6000 psi).
Is methyl methacrylate soluble in water?
Water
Methyl methacrylate/Soluble in
Is methacrylic acid hydrophobic?
The most hydrophobic polymer, MA/MMA/MAA (4.5:4.5:1), remained essentially unchanged between pH 5.0 and 7.4.
