概要 | Allylated pyrogallol (A3PG) and acrylated pyrogallol(Ac3PG) as bio-based trienes, and allylated gallic acid (A4GA) and acrylated allyl gallate (Ac3A1GA) as bio-based tetraenes were synthesized. Thiol-ene photopolymerizations of the biobased polyenes and a pentaerythritol-based primary tetrathiol (pS4P) produced photo-cured resins (A3PG-pS4P, Ac3PG-pS4P, A4GApS4P and Ac3A1GA-pS4P). The FT-IR spectral analysis revealed that thiol-ene reactions of thiol/allyl and thiol/acryloyl groups smoothly proceeded. Gel fractions of acryl-based cured resins were a little higher than those of allyl-based cured resins. GA- and acryl-based cured resins exhibited higher crosslinking densities than PG- and allyl-based cured resins, respectively. A higher order of tan δ peak temperature was Ac3PG-pS4P > Ac3A1GApS4P>A4GA-pS4P>A3PG-pS4P. Ac3PG-pS4P displayed the highest 5 % weight loss temperature, tensile strength and tensile modulus among all of the cured resins. |
