For this purpose, the SBO possessing primary hydroxyland bromide functionalities (Br-SBO-OH) is prepared from epoxidized soybean oil(ESBO) by ring-opening reaction catalyzed by hydrochloric acid. The photo-inducedmetal-free atom transfer radical and ring-opening photopolymerizations (PIMF-ATRP and PIMF-ROP) of tertiary butylacrylate (t-BA) and epsilon-CL monomers are concurrently performed on the Br-SBO-OH bifunctional macro photo-initiator without affecting each other, using perylene as an organic photo-catalyst (lambda= 400-500 nm). The t-BA groups of resulting bio-based PtBA-SBO-PCL is hydrolyzed into acrylic acid moieties via acidolysisto achieve the ultimate PAA-SBO-PCL. Spectroscopic, chromatographic,wettability and thermal investigations such as FT-IR, H-1-NMR, GPC,WCA, TGA and DSC analyses indicate that both the required intermediates and thetargeted polymers are successfully synthesized, as well as the conversion of t-BA groups to acrylic acid units. Thus,this efficient and most importantly green and sustainable process that can beenabled to production of a variety of SBO-based heterograft copolymers could greatly expand the potential applications of widely used polymers as advanced materials.en10.1007/s10924-022-02630-yinfo:eu-repo/semantics/closedAccessPhotopolymerizationAtom Transfer Radical PolymerizationRing-Opening PolymerizationSoybean OilThermal PropertiesControlled/Living Radical PolymerizationBlock-CopolymersNanoparticlesWettabilityTemperaturePolymersMonomersRouteArticle311102111Q1WOS:0008711723000032-s2.0-85140327437Q1
