Polyepichlorohydrin (PECH) is a functional polyether first synthesized in the 1950's by the
catalytic ring opening polymerization of epichlorohydrin (ECH), its inexpensive epoxide pre …

This paper discusses methods of using biomass from the agriculture, forestry, food and
aquaculture industries as potential raw materials for bio-polyols and as fillers in the …

In response to the environmental impacts of conventional polyurethane adhesives derived
from fossil fuels, this study introduces a sustainable alternative utilizing lignin-based polyols …

Bio-polyols, produced by liquefying lignin with polyhydric alcohols, offer a promising
alternative to conventional polyols for polyurethane production. To enhance the …

Lignin represents the most abundant natural source of aromatic scaffolds. The majority of
lignin is obtained as byproduct from industrial pulping. However, since lignin is often burned …

In order to diminish the dependence on oil lignin, which is the most abundant biopolymer of
phenolic origin on Earth and can be utilised in different industrial endeavours, such as, the …

The valorization of lignin in polyurethane products allows biorefineries and paper industries
to use this biomass with some added value and not waste most of it in combustion to …

Abstracts In this study, the intrinsic brittleness of poly (lactic acid)(PLA) was overcome by
chemical modification using ethyl acetate-extracted lignin (EL) via cationic ring-opening …

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 …

Traditional phenol-formaldehyde resin involves the use of petrochemical-based phenol and
formaldehyde as feedstocks, raising environmental and health concerns. Herein, renewable …
