Abstract

ABSTRACT: 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. © 2016 Wiley Periodicals, Inc. J.

Chem.2017, 55, 801–807 Abstract : A new di‐ tert ‐butyl acrylate monomer is designed for use in copper(II)‐mediated radical photopolymerization and displays excellent chain‐end fidelity at very high monomer conversions. This leads to di‐acrylic acid polymers that possess higher carboxylic acid density and increased functional group mobility compared to traditional poly(acrylic acid) systems. Additionally, the monomer readily copolymerizes with tert ‐butyl acrylate to permit the engineering of these acrylate polymers with tunable control over charge distribution.
