The name “2-Methylpropyl 2-methyl-2-propenoate” is the systematic IUPAC name for Isobutyl methacrylate, a colorless, flammable liquid with a fruity odor that is used as a monomer in the production of polymers and resins. 
These polymers are often used in paints, coatings, adhesives, and plastics due to their excellent clarity, flexibility, and weather resistance.
2-Methylpropyl 2-methyl-2-propenoate is the IUPAC name for a compound more commonly known as isobutyl methacrylate. 

2-Methylpropyl 2-methyl-2-propenoate is an organic ester formed through the esterification of methacrylic acid (2-methyl-2-propenoic acid) with isobutanol (2-methylpropan-1-ol). 
The molecule consists of a methacrylate backbone, which contributes reactivity, and an isobutyl group, which imparts steric bulk and hydrophobic character.
In industry, 2-Methylpropyl 2-methyl-2-propenoate is valued for its ability to copolymerize with other acrylic or methacrylic compounds, creating materials with tailored physical and chemical properties. 

Its structure provides both rigidity (from the methacrylate group) and flexibility (from the branched isobutyl group), which is useful for balancing durability and softness in finished products.
Because of its volatile and flammable nature, it must be handled with care, especially during storage and processing, typically under inhibited conditions (such as with hydroquinone, HQ) to prevent unwanted polymerization.

2-Methylpropyl 2-methyl-2-propenoate is a versatile and reactive ester compound, widely used in modern industrial chemistry for the production of flexible, durable, and weather-resistant polymeric materials.
2-Methylpropyl 2-methyl-2-propenoate is a branched-chain ester that results from the condensation of methacrylic acid, a carboxylic acid with a double bond (2-methyl-2-propenoic acid), and isobutanol (2-methylpropan-1-ol), a branched-chain primary alcohol. 
The name reflects its molecular structure: the “2-methylpropyl” part represents the isobutyl group derived from the alcohol, while the “2-methyl-2-propenoate” portion denotes the methacrylate group derived from the acid.

2-Methylpropyl 2-methyl-2-propenoate belongs to the broader family of methacrylate esters, which are known for their ability to undergo free-radical polymerization, forming tough, glassy, transparent, and weather-resistant polymers. 
Among the methacrylates, the isobutyl derivative is notable for its balance between flexibility and rigidity, due to the steric hindrance provided by the branched isobutyl side chain. 
This feature makes the resulting polymers less brittle and more impact-resistant than those made from simpler methacrylates like methyl methacrylate.
