Özet
A photo-induced and completely metal catalyst-free synthetic pathway isproposed for the preparation of bio-based heterograft copolymer based on poly(acrylicacid) (PAA) and poly(ɛ-caprolactone) (PCL) pendant groups on the soybean oil (SBO)backbone (PAA-SBO-PCL). 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-ATRPand PIMF-ROP) of tertiary butylacrylate (t-BA) and ɛ-CL monomersare concurrently performed on theBr-SBO-OH bifunctional macro photo-initiator without affecting each other, usingperylene as an organic photo-catalyst (λ= 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, 1H-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 couldgreatly expand the potential applications of widely used polymers as advancedmaterials.
