Descrizione generale
-Methylstyrene is an aromatic alkyl-substituted styrene monomer with a relatively high boiling point. It is widely used as a monomer to synthesize thermoplastic composite resins applied in adhesives, and coatings that require high-temperature stability. It can also participate as a precursor in regioselective and diastereoselective synthesis of natural products, pharmaceuticals, and other structurally diverse compounds.
Applicazioni
α-Methylstyrene can be used:
- As a monomer to prepare “Phene” monomer for photopolymerizable dental resin composites to reduce their polymerization shrinkage. α-Methylstyrene has a low double bond concentration suitable for the preparation of low volumetric shrinkage and shrinkage stress resilient resin composites.
- As a monomer to prepare poly(α-methylstyrene) polymer which can be used as an additive to fabricate organic thin film transistors. This polymer promotes the growth of uniformly aligned semiconductor crystals with significantly improved orientation.
- As a precursor to synthesize 3,4-dihydropyrans with therapeutic potential.
