Fully Renewable Pressure-Sensitive Adhesive System Derived from ε‑Decalactone, L‑Lactide, Epoxidized Soybean Oil, and Rosin Ester |
초록 |
Pressure-sensitive adhesives (PSAs) are prepared with plant-based thermoplastic polyester elastomers (TPPEs), rosin ester tackifier, and epoxidized soybean oil plasticizer. Controlled bulk ring-opening transesterification polymerization of ε-decalactone and L-lactide using diethylene glycol as an initiator gives ABA type block polyesters via a one-pot, two-step process with only tin(II) ethylhexanoate. Three semicrystalline poly(L-lactide)−poly(ε-decalactone)−poly(L-lactide) (PLLA−PDL−PLLA) triblock copolymers are prepared containing 100 kg mol−1 PDL midblocks and 8−30 wt % PLLA end blocks with narrow dispersities. The triblocks are combined with the tackifier of 50 wt % and the plasticizer of 15−30 wt %. The thermal, viscoelastic, mechanical and morphological properties of the elastomers and the adhesive formulations are determined. These novel materials could hold promise for sustainability and high adhesive performance. |
