Biosourced All-Acrylic ABA Block Copolymers with Lactic Acid-Based Soft Phase 2020 Access copy available to the general public Unrestricted Lactic acid is one of the key biobased chemical building blocks, given its readily availability from sugars through fermentation and facile conversion into a range of important chemical intermediates and polymers. Herein, well-defined rubbery polymers derived from butyl lactate solvent were successfully prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization of the corresponding monomeric acrylic derivative. Good control over molecular weight and molecular weight distribution was achieved in bulk using either monofunctional or bifunctional trithiocarbonate-type chain transfer agents. Subsequently, poly(butyl lactate acrylate), with a relative low Tg (-20 °C), good thermal stability (5% wt. loss at 340 °C) and low toxicity was evaluated as a sustainable middle block in all-acrylic ABA copolymers using isosorbide and vanillin-derived glassy polyacrylates as representative end blocks. Thermal, morphological and mechanical properties of copolymers containing hard segment contents of <20 wt% were evaluated to demonstrate the suitability of rubbery poly(alkyl lactate) building blocks for developing functional sustainable materials. Noteworthy, 180° peel adhesion measurements showed that the synthesized biosourced all-acrylic ABA copolymers possess competitive performance when compared with commercial pressure-sensitive tapes. info:eu-repo/grantAgreement/ES/DGA/B25-20R info:eu-repo/grantAgreement/ES/ISCIII/CPII13-00017 info:eu-repo/grantAgreement/ES/ISCIII-ERDF-ESF/PI18-00349-Investing in your future info:eu-repo/grantAgreement/ES/MCIU/MAT2017-82669-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.411 2020 CHEMISTRY, MULTIDISCIPLINARY 63 / 178 = 0.354 2020 Q2 T2 BIOCHEMISTRY & MOLECULAR BIOLOGY 116 / 297 = 0.391 2020 Q2 T2 0.782 2020 Analytical Chemistry 2020 Q1 Chemistry (miscellaneous) 2020 Q1 Drug Discovery 2020 Q1 Physical and Theoretical Chemistry 2020 Q1 Molecular Medicine 2020 Q1 Organic Chemistry 2020 Q1 Pharmaceutical Science 2020 Q1 Medicine (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-4726-7821 Jiménez-Alesanco, A.
