Lignin is the most abundant aromatic natural polymer,and receiving great attention in replacing various petro-leum-based polymers.The aim of this study is to investigate the feasibility of technical lignin as a polyol...
Non-isocyanate polyurethane(NIPU)foams from a commercial hydrolysable tannin extract,chestnut wood tannin extract,have been prepared to determine what chemical species and products are taking part in the reactions inv...
Polyols are groups of organic compounds which contain carbon and are randomly linked to other atoms,especially carbon-carbon and carbon-hydrogen.These compounds are mainly used as reactants to make other polymers.Amon...
The aim of this research work was to evaluate the potential of using renewable natural feedstock,i.e.,Jatropha curcas oil(JCO)for the synthesis of non-isocyanate polyurethane(NIPU)resin for wood composite applications...
ABSTRACT Non-isocyanate polyurethane(NIPU)foams using a hydrolysable tannin,also vulgarly called tannic acid,namely here commercial chestnut wood tannin extract was prepared.Compression strength did not appear to depe...

With the current trend of increasing efforts to develop non-isocyanate-based polyurethanes(NIPUs),this study aimed to check the feasibility of the development of a method using cyclic carbonate modified catechin and a...
Soy-protein isolate(SPI)was used to prepare non-isocyanate polyurethane(NIPU)thermosetting adhesives for wood panels by reacting it with dimethyl carbonate(DMC)and hexamethylene diamine.Both linear as well as branched...
This research was financed by the ERA-CoBioTech project WooBAdh(Environmentally-friendly bioadhesives from renewable resources).The University of Ljubljana,Biotechnical Faculty was financed by the Slovenian Ministry of Education,Science and Sport and the Slovenian Research Agency within the framework of program P4-0015.The LERMAB was financed by the French Agence Nationale de la Recherche(ANR)as part of the laboratory of excellence(LABEX)ARBRE.
A non-isocyanate-based polyurethane(NIPU)wood adhesive was produced from organosolv lignin,which is a bio-sourced raw material,available in large quantities and produced as a by-product of the paper industry.The formu...
