Over the last few years, waterborne polyurethane (WPU) was applied to various fibers,
adhesives, primers for metals, caulking materials, emulsion polymerization media, paint …

Natural rubber (NR) 1 is a biopolymer mainly composed of isoprene units linked to form
double bonds with cis configuration. After the vulcanization process, NR is widely employed …

Chain-end modification of low molar mass polybutadienes allowed the formation of
thermoreversible networks based on the Diels–Alder chemistry. Furan telechelic …

A novel melt transurethane polycondensation route for polyurethanes under solvent‐free
and nonisocyanate condition was developed for soluble and thermally stable aliphatic or …

Presently, the disposal of thousands of tons of waste tyres produced every year in the whole
world is a major environmental problem. Since tyre rubbers do not decompose easily on …

This work involved the development of a synthetic method to produce a novel bio-based
triblock copolymer (PLA-NR-PLA) that consisted of poly (lactic acid) and natural rubber. The …

A strategy aiming to decrease the amount of isocyanate in the PU industries without
changing their current facilities is proposed. Hydroxyl terminated non-isocyanate …

A series of new waterborne polyurethanes (WPUs) was successfully prepared by
prepolymer process from renewable source, hydroxytelechelic natural rubber (HTNR), with …

Telechelic oligoisoprenes were successfully prepared by the selective controlled
degradation of natural rubber, a renewable source, via epoxidation and cleavage reactions …

New crosslinked ionic polyurethanes and copolyurethanes were yielded by reaction of
telechelic cis-1, 4-oligoisoprenes, bearing a variable number of ammonium and hydroxy …
