Thermoplasticization of lignin was achieved by the acylation of polyfunctional lignin yielded in the course of the alkali cooking of wood tips. The kneading of acylated lignin and poly(ε-caprolactone) gave the composite film with reasonable flexibility and light blocking property which might provide several utilization ways of lignin to serve as substitution of petroleum products. The un-acylated (virgin) lignin also gave flexible, thermoplastic composites with polypropylene (PP) when maleate-modified PP co-existed.
