This research focuses on synthesis and modification of polyol precursors derived from cis-1,4-polyisoprene (PI). These new polyol precursors can be converted to high value-added polyurethane (PU). The epoxidized hydroxytelechelic PI (EHTPI) prepared

New photosensitive oligoisoprenes were synthesized by controlled degradation of high molecular weight cis-1,4-polyiso- prene and successive chemical modification of the chain-ends. Oligomers with diacrylate extremities were synthesized, characterized

A new type of polyurethane (PU) has been synthesized by using hydroxyl terminated liquid natural rubber (HTNR) and poly(e-caprolactone) (PCL) as a soft segment and toluene-2,4 diisocyanate (TDI) as a hard segment. This PU becomes a biodegradable and

A novel linker for the immobilisation of alcohols on solid support is described. This linker can be cleaved either enzymatically using penicillin amidase, or by very mild acid hydrolysis using 10% TFA.

We investigate the one-pot synthesis of a new α,ω-bistrithiocarbonyl-end functionalized telechelic cis-1,4-polyisoprene (Pip) via metathesis degradation from natural rubber (NR) in the presence of the Grubbs second generation catalyst (GII) and a b
