'''Acrylic resins''' are a group of related [[thermoplastic]] or [[thermosetting plastic]] substances derived from [[acrylic acid]], [[methacrylic acid]] or other related compounds.<ref>[http://www.thefreedictionary.com/acrylic+resin acrylic resin definition, TheFreeDictionary quoting The American Heritage® Dictionary of the English Language]</ref> [[Polymethyl acrylate]] is an acrylic resin used in an [[emulsion|emulsed]] form for [[lacquer]], [[textile]] finishes, [[adhesives]] and, mixed with [[clay]], to gloss paper.

== What is acrylic resin? ==
Acrylic resin is a general term for any one of the plastics (resin) generated through chemical reaction by applying [[polymerization]] initiator and heat to a [[monomer]].

The chemical name for the resin produced from the [[Methyl methacrylate]] monomer (MMA) is [[Acrylic glass|Polymethyl methacrylate]] (PMMA). MMA is a transparent and colorless fluid substance.<ref>[http://www.epa.gov/ttn/uatw/hlthef/methylme.html  Methyl Methacrylate] epa.gov, 2000, 'a colorless, volatile, flammable liquid that is soluble in warm water'</ref> One of the main characteristic features of PMMA is its high transparency. With its high weather resistance, it does not easily turn yellow or crumble by sunlight. Polymethyl methacrylate are used not only for transparent windows in aquariums but also for various items such as signboards in places like convenience stores, taillights of automobiles, cell phone display screens, backlight optical waveguides for [[liquid crystal displays]] (LCD) and so on.<!-- there must be more on resins than just PMMA -->
