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.
Copolymers consisting partially of methacrylic acid are used in certain types of tablet coatings in order to slow the tablet's dissolution in the digestive tract, and thus extend or delay the release of the active ingredient. [8] MAA occurs naturally in small amounts in the oil of Roman chamomile. [citation needed]
Soft contact lenses are often made of a related polymer, where acrylate monomers containing one or more hydroxyl groups make them hydrophilic. In orthopedic surgery, PMMA bone cement is used to affix implants and to remodel lost bone. [41] It is supplied as a powder with liquid methyl methacrylate (MMA).
In 2005, The Dream became the first Emirati film to be distributed in cinemas across UAE. Meanwhile, the UAE began to attract South Asian films and television serials, mainly Bollywood and Lollywood productions.

The thriller doubles as a journalism movie, too, with Kirsten Dunst turning in an outstanding performance as a world-weary photographer who takes a rookie (Cailee Spaeny) under her wing on the ...
The company made a public announcement on 19 March 2022, confirming the project. [9] However, the following January, Vignesh was reported to be replaced. [ 10 ] Reports claimed it was due to Ajith not being impressed with the script after the director had developed it during the pre-production for six months.
Most polyolefin are made by treating the monomer with metal-containing catalysts. The reaction is highly exothermic. Traditionally, Ziegler-Natta catalysts are used. Named after the Nobelists Karl Ziegler and Giulio Natta, these catalysts are prepared by treating titanium chlorides with organoaluminium compounds, such as triethylaluminium.
A polymer (/ ˈ p ɒ l ɪ m ər / [4] [5]) is a substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeating subunits derived from one or more species of monomers. [6]
