  2. Wagner-Jauregg reaction - Wikipedia

    en.wikipedia.org/wiki/Wagner-Jauregg_reaction

    Styrene maleic anhydride copolymer is formed, retaining the aromaticity of the styrene. The Diels–Alder product can be re-aromatized using elemental sulfur at high temperature, followed by a second rearomatization by decarboxylation with barium hydroxide and copper: [3] Wagner-Jauregg reaction

  3. Functionalized polyolefins - Wikipedia

    en.wikipedia.org/wiki/Functionalized_polyolefins

    One of the most common way to attach functionality onto a preexisting polymer backbone is through free radical reaction. Free radicals can be formed through plasma, peroxide initiation, etc. [3] When there is a free radical on the polyolefin chain, maleic anhydride [4] can be attached to promote

  4. Polybutadiene - Wikipedia

    en.wikipedia.org/wiki/Polybutadiene

    Polybutadiene [butadiene rubber, BR] is a synthetic rubber. It offers high elasticity, high resistance to wear, good strength even without fillers, and excellent abrasion resistance when filled and vulcanized. "Polybutadiene" is a collective name for homopolymers formed from the polymerization of the monomer 1,3-butadiene.

  5. Butadiene - Wikipedia

    en.wikipedia.org/wiki/Butadiene

    It is a partner in Diels–Alder reactions, e.g. with maleic anhydride to give tetrahydrophthalic anhydride. [29] Like other dienes, butadiene is a ligand for low-valent metal complexes, e.g. the derivatives Fe(butadiene)(CO) 3 and Mo(butadiene) 3.

  6. Polyolefin - Wikipedia

    en.wikipedia.org/wiki/Polyolefin

    An alpha-olefin (or α-olefin) is an alkene where the carbon-carbon double bond starts at the α-carbon atom, i.e. the double bond is between the #1 and #2 carbons in the molecule. Alpha-olefins such as 1-hexene may be used as co-monomers to give an alkyl branched polymer (see chemical structure below), although 1-decene is most commonly used ...

  7. Frontier molecular orbital theory - Wikipedia

    en.wikipedia.org/wiki/Frontier_molecular_orbital...

    In terms of the stereoselectivity of the reaction between maleic anhydride and cyclopentadiene, the endo-product is favored, a result best explained through FMO theory. The maleic anhydride is an electron-withdrawing species that makes the dieneophile electron deficient, forcing the regular Diels–Alder reaction.

  8. Maleic anhydride - Wikipedia

    en.wikipedia.org/wiki/Maleic_anhydride

    Maleic anhydride is a classic substrate for Diels-Alder reactions. [9] It was used for work in 1928, on the reaction between maleic anhydride and 1,3-butadiene, for which Otto Paul Hermann Diels and Kurt Alder were awarded the Nobel Prize in 1950. It is through this reaction that maleic anhydride is converted to many pesticides and pharmaceuticals.

  9. Alkenylsuccinic anhydrides - Wikipedia

    en.wikipedia.org/wiki/Alkenylsuccinic_anhydrides

    The patent describes the reaction of the alkenes with excess maleic anhydride at 200 °C in an autoclave. The excess alkene is removed by distillation in vacuo, the resulting alkenyl succinic anhydride hydrolyzed with dilute sodium hydroxide solution and the disodium salt reacted with an acid to achieve an alkenebutanedioic acid.
