UV curable soybean‐oil hybrid systems based on thiol‐acrylate and thiol‐ene‐acrylate chemistry

In this study, epoxidized soybean oil was modified to prepare acrylated epoxidized soybean oil (AESO) and vinyl/acrylate ended soybean oil (VASO), which were blended with mercaptopropyl polyhedral oligomericsilsequioxane (POSS‐SH) to prepare UV curable thiol‐acrylate and thiol‐ene‐acrylate hybrid coatings. Photopolymerization processes of the coatings were measured and the results showed that addition of POSS‐SH obviously increased the conversion of double bond. The physical and mechanical properties of all cured samples were investigated, which indicated that the pencil hardness, tensile strength, and fracture toughness were significantly improved by POSS‐SH. Moreover, with increasing POSS‐SH content, the water contact angles of cured samples were increased, and the water resistance was greatly improved. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Effects of Introducing Crude and Modified Soybean Oil into Polyurethane Structures on the Soil-Burial Biodegradation Process

Synthetic and natural acrylate oligomers blends and their blends with different ratios of crude soybean oil were studied as environmentally degradable and eco-compatible materials.

Effect of acrylation on the properties of waterborne epoxy: evaluation of physicochemical,thermal, mechanical and morphological properties

The present work addresses the critical requirements for the coating industry such as developing the sustainability of biobased materials and simultaneously achieving a balanced combination of coating properties. In this study, acrylated epoxidized soybean oil (AESO) has been successfully synthesized from epoxidized soybean oil and acrylic acid. Subsequently, AESO was modified using a biobased long chain diacid (Pripol-1009) with the assistance of a water/ethanol blend to form waterborne epoxy acrylate (WBEA). The properties of the cured WBEA with 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane as initiator were studied through spectral analysis, coating properties evaluation, corrosion resistance, and morphological and thermal analysis. The results revealed that WBEA exhibited relatively better mechanical, thermal and corrosion resistance characteristics over cured waterborne epoxy.     

Facile functionalization of soybean oil by thiol-ene photo-click reaction for the synthesis of polyfunctional acrylate

Nowadays biosource-based materials have received revitalized interest for their ability to substitute for petrochemical-based materials. In this paper, we report a facile synthetic method of soybean oil-based polyfunctional acrylate (PFA) for UV-curable materials. Specifically, rapid and highly efficient side-chain functionalization of soybean oil was achieved via photoclick thiol-ene reaction, soybean oil-based polycarboxylic acid (PCA) was thus obtained. Next, by DCC (N,N′-dicyclohexylcarbodiimide) catalyzed esterification reaction with hydroxypropyl acrylate, polyfunctional acrylate (PFA) was synthesized at room temperature. Real-FTIR result indicated that almost 100% conversion of double-bond within vegetable oil was observed within 16.7 min, yielding the soybean oil-based polycarboxylic acid quantitatively. Furthermore, the structure of PFA was confirmed by ¹H NMR and FTIR. Finally, the excellent UV-curing rate of PFA was revealed by real-FTIR.     

Development of soy-based UV-curable acrylate oligomers and study of their film properties

Bio-based coating materials have emerged as an environmentally friendly alternative to petrochemical based ones due to their sustainability, lower carbon footprint and often lower cost. Acrylated vegetable oils and their derivatives are increasingly preferred for advanced photo-curable “green” coatings due to a number of technical and commercial benefits. We report a novel family of acrylate-functional monomers/oligomers derived from epoxidized soybean oil (ESO) and epoxidized soy-methyl ester (EME), using 2-hydroxyethyl acrylate (HEA) as an acrylating agent. Using super-acid catalyzed etherification, acrylated soy-monomers and oligomers with lower viscosity and high acrylate content have been synthesized. Soy-acrylate products are characterized for their chemical structures and functionality using chemical, physical and spectroscopic methods.
