Microwave-Assisted Syntheses in Recyclable Ionic Liquids: Photoresists Based on Renewable Resources

The copoly(2-oxazoline) pNonOx(80)-stat-pDc(=)Ox(20) can be synthesized from the cationic ring-opening copolymerization of 2-nonyl-2-oxazoline NonOx and 2-dec-9′-enyl-2-oxazoline Dc(=)Ox in the ionic liquid n-hexyl methylimidazolium tetrafluoroborate under microwave irradiation in 250 g/batch quanti...

Descripción
Sumario:The copoly(2-oxazoline) pNonOx(80)-stat-pDc(=)Ox(20) can be synthesized from the cationic ring-opening copolymerization of 2-nonyl-2-oxazoline NonOx and 2-dec-9′-enyl-2-oxazoline Dc(=)Ox in the ionic liquid n-hexyl methylimidazolium tetrafluoroborate under microwave irradiation in 250 g/batch quantities. The polymer precipitates upon cooling, enabling easy recovery of the polymer and the ionic liquid. Both monomers can be obtained from fatty acids from renewable resources. pNonOx(80)-stat-pDc(=)Ox(20) can be used as polymer in a photoresist (resolution of 1 μm) based on UV-induced thiol–ene reactions.
