Description

General description

Dibutyl itaconate (DBI) is an itaconate ester that can be prepared by an itaconic acid precursor.

Application

DBI is a monomer that can be copolymerized with pyridine groups to form nanocomposites for the development of bio-based elastomers. Copolymerization of DBI with acrylated epoxidized soya oil (AESO) can produce a thermoset material which finds potential applications in the modification of fatty acids.
