Poly(methyl methacrylate) - Wikipedia

N2 - 2,3,4,5,6-Pentafluoro and 4-trifluoromethyl 2,3,5,6-tetrafluoro styrenes were readily copolymerized with methyl methacrylate (MMA) by a free radical initiator. The copolymers were soluble in tetrahydrofuran and acetone. The films obtained were transparent and flexible. The glass transition temperatures (Tgs) of the copolymers were found positively deviated from the Gordon-Taylor equation. The positive deviation could be accounted for by dipole-dipole intrachain interaction between the methyl ester group of MMA and the highly fluorinated aromatic moiety, which resulted in a decrease in the segmental mobility of the polymer chains and the enhanced Tg values of the copolymers. The water absorption of PMMA was greatly decreased by copolymerization of MMA with the highly fluorinated styrenes. With as little as 10 mol % of pentafluoro styrene content in the copolymer, the water absorption was decreased to one-third of that for pure PMMA. The fluorinated styrenes-MMA copolymers were thermally stable up to 420 °C under air and nitrogen atmospheres. With 50 mol % of MMA in the copolymer, the copolymer was still stable up to 350 °C. Since these copolymers contain a large number of fluorine atoms, the light absorption in the region of the visible to near infrared is decreased in comparison with nonfluorinated polymers. Thus, these copolymers may be suitable for application in optical devices, such as optical fibers and waveguides.

This review presents a screening evaluation of a route to methyl methacrylate that starts from ethylene and combines the two developments noted above. Our estimates indicate that for a 250 million lb/yr plant such a route appears to be more economical than the currently used one via acetone cyanohydrin, but to be somewhat less attractive than the route to methyl methacrylate which starts from isobutylene or t-butanol.

Methyl methacrylate can be made by the reaction of methyl propionate with formaldehyde. In this review, we assess developments which would increase the attractiveness of such a process.

Methanol is a common industrial chemical that has been usedas an alternative blended liquid transportation fuel and under considerationfor wider use. In the USA its application profile in 1998 was MTBE, 36 percent;formaldehyde, 24 percent; acetic acid, 10 percent; solvents, 6 percent;chloromethanes, 4 percent; methyl methacrylate, 3 percent; miscellaneous,including methylamines, glycol methyl ethers, dimethyl terephthalate,antifreeze and fuels, 17 percent. In many countries, notably in Asia, methanolis almost exclusively used to produce the intermediate chemical formaldehyde asinput to urea formaldehyde composite wood adhesive.

Can be used to embed tissue for thin or thick sectioning. By varying butyl methacrylate amount in embedding mix, block hardness is changed. Can be UV catalyzed. For use in electron microscopy.

methyl methacrylate 80-62-6 Route Of Synthesis - …

Hybrid organic-inorganic membranes were fabricated using sol-gel technique using poly(methyl methacrylate) (PMMA) and tetraethyl orthosilicate (TEOS) with 80/20 (w/w) ratios with THF solvent. The thin films were then characterized using FTIR, SEM, EDX, DSC, TGA, water permeability and also its molecular weight cut-off. From the preliminary characterization, the hybrid membrane was found to have nano and ultra scale tight pore ranges. FT-IR spectroscopy uncovered all the signature peaks characteristic of silicate structures in the near-surface regions. Fingerprints of Si{single bond}O{single bond}Si groups in cyclic and linear molecular substructures are present. The SEM image clearly shows that hybrid membranes have homogenous and smooth surface. EDX analysis shows the composition of particles in the membrane. DSC analysis of the membrane shows interesting phenomenon regarding glass transition temperature (Tg). The hybrid membrane was found to have higher Tg than pure PMMA. From TGA analysis, the hybrid membranes were observed to have higher thermal stability than pure PMMA.
