A di-tert-butyl acrylate monomer for controlled radical photopolymerization

26 November 2016

A new di-tert-butyl acrylate (diTBA) monomer for controlled radical polymerization is reported. This monomer complements the classical use of tert-butyl acrylate (TBA) for synthesis of poly(acrylic acid) by increasing the density of carboxylic acids per repeat unit, while also increasing the flexibility of the carboxylic acid side-chains. The monomer is well behaved under Cu(II)-mediated photoinduced controlled radical polymerization and delivers polymers with excellent chain-end fidelity at high monomer conversions. Importantly, this new diTBA monomer readily copolymerizes with TBA to further the potential for applications in areas such as dispersing agents and adsorbents.
