NMR spectroscopic data and SEC data for the synthesis of Lignin-Polycaprolactone Copolymers were deposited.

Bruker Avance II (400 MHz)

Viscotek GPCmax VE-2001 with a flow rate of 1 ml min-1 at 25 °C with THF as mobile phase. The system was equipped with two Malvern Viscotek T columns (porous styrene divinylbenzene copolymer) with a maximum pore size of 500 Å and 5000 Å, a HPLC pump, a refractive index detector (VE-3580), and a viscometer (Viscotek 270 Dual detector). The results were evaluated using a conventional calibration using polystyrene standards. The respective molecular weights are given in polystyrene equivalents.
