Abstract

Telah dilakukan penelitian pembuatan poliurethane alam dari isolasi lignin kayu sembarang, hasil menunjukkan bahwa ada peningkatan sifat mekanik dengan bertambahnya kadar toluena diisosianat, perbandingan isosinat yang baik adalah 2 : 1. Pengujian gugus C=O dari poliurethane alam menggunakan Forier Transform infra red spektroscopy dan terlihat gugus urthane dari C=O pada panjang gelombang 2270,20 cm -1.
