General Information about Polymethacrylate. Polymethacrylates Properties. Polymethacrylates are amorphous commodity thermoplastics of high transparency that can be easily processed and converted into many semi-finished products like films, rods, tubes, and sheets.
The principal application, consuming approximately 75% of the MMA, is the manufacture of polymethyl methacrylate acrylic plastics . Methyl methacrylate is also used for the production of the co-polymer methyl methacrylate-butadiene-styrene (MBS), used as a modifier for PVC.
Poly(methyl Methacrylate) Polymethylmethacrylate (PMMA) is a non-cross linked polymer and has a lower modulus of elasticity than a cross-linked dimethacrylate or epoxy polymers, which leads to better elastic recovery properties.
Poly(methyl methacrylate) is within the scope of WikiProject Polymers which aims to improve the coverage of polymer-related articles in Wikipedia.If you are interested, you may visit the project page and join with us. Feel free to leave messages at the project talk page.
Poly(methyl methacrylate) (PMMA) and polystyrene (PS)/clay nanocomposites were prepared via in-situ bulk polymerization. The compatibility of the initiator and monomer with the clay surface was found to profoundly affect the clay dispersion. By using a surfactant containing a polymerizable group to modify the clay surface, exfoliated PMMA and PS/clay …
Mar 19, 2013· Poly(methyl methacrylate), PMMA, is known as Plexiglas in 20 th century, is an amorphous, transparent and colourless thermoplastic. PMMA is hard and stiff but brittle and notch-sensitive, with a glass transition temperature of 105°C.
Methyl Methacrylate Poly(methyl methacrylate) b.p. = 100°C Because of the excellent optical properties, weather resistance, light weight, impact and shatter resistance (compared to inorganic glass), dimensional stability, heat resistance, and processability, PMMA has many profound and diverse uses that affect our lives every day.
Poly(methyl methacrylate) nanoparticles are synthesized via differential microemulsion polymerization, where the monomers in the reaction system are kept at very low concentrations by continuous differential addition.
In this work, poly (methyl methacrylate) nanocomposites containing silicon carbide nanofillers (untreated or treated with a silane surface compatibilizing) were investigated and characterized to be used to production of innovative products which can be …
poly(methyl methacrylate), but softer than it, because its long polymer chains are thinner and smoother and can more easily slide past each other. Poly(methyl methacrylate) is produced by free‐radical polymerization of methyl‐ methacrylate in mass (when it is in sheet form) or suspension polymerization according to the following chart ...
Sigma-Aldrich offers a number of Poly(methyl methacrylate) products. View information & documentation regarding Poly(methyl methacrylate), including CAS, MSDS & more.
Poly(methyl methacrylate) (PMMA) is a transparent thermoplastic, often used as a light or shatter-resistant alternative to glass.It is sometimes called acrylic glass.Chemically, it is the synthetic polymer of methyl methacrylate.The material was developed in 1928 in various laboratories, and was first brought to market in 1933 by Rohm and Haas Company, under the …
Poly(methyl methacrylate) – so-called 'acrylic resin' – is usually the material of choice for full denture bases and 'gumwork' for removable devices. It has also been the chemical model for many other material developments in dentistry, such as restorative materials.
Poly(methyl methacrylate) (PMMA) has excellent transparency and high modulus, but its melt viscosity is on a significantly higher side (>10 4 Pa s). It is also reported that mechanical properties of PMMA such as abrasion and wear are relatively low and independent of molecular weight.
Poly(methyl acrylate) (PMA) is a hydrophobic synthetic acrylate polymer.PMA, though softer than polymethyl methacrylate (PMMA), is tough, leathery, and flexible.
In this work, poly (methyl methacrylate) nanocomposites containing silicon carbide nanofillers (untreated or treated with a silane surface compatibilizing) were investigated and characterized to be used to production of innovative products which can be films, covers and materials with better optical properties.
Poly(methyl methacrylate) - boehmitenano composites were synthesized by direct semicontinue microemulsion polymerization combined with the in-situ sol-gel preparation method. Divinylbenzene was used as a cross-linking agent of the polymer chains in order to improve the physicochemical properties of the nanocomposites.

We describe the development and application of a novel carbon nanotube/poly(methyl methacrylate) (CNT/PMMA) composite electrode as a sensitive amperometric detector of microchip capillary electrophoresis (CE).
Poly(methyl methacrylate) (PMMA), also known as acrylic, acrylic glass, or plexiglass as well as by the trade names Crylux, Plexiglas, Acrylite, Lucite, Perclax and Perspex among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. The same material can ...
Poly(methyl methacrylate)-block-poly(n-butyl acrylate)-block-poly(methyl methacrylate) triblock copolymers (MnBM) have been synthesized by the sequential controlled radical polymerization (atom transfer radical polymerization, ATRP) of n-butyl acrylate (n-BuA) followed by methyl methacrylate (MMA). The polymerization of n-BuA has been first initiated by the difunctional (diethyl meso-2,5 ...
Polymethyl methacrylate (PMMA), a synthetic resin produced from the polymerization of methyl methacrylate. A transparent and rigid plastic, PMMA is often used as a substitute for glass in products such as shatterproof windows, skylights, illuminated signs, and aircraft canopies. It is sold under
