Terpene and dextran renewable resources for the synthesis of amphiphilic biopolymers
Abstract : The present work shows the synthesis of amphiphilic polymers based on the hydrophilic
dextran and the hydrophobic terpenes as renewable resources. The first step concerns the
synthesis of functional terpene molecules by thiol-ene addition chemistry involving amino- or
carboxylic acid thiols and dihydromyrcenol terpene. The terpene modified polysaccharides
were subsequently synthesized by coupling the functional terpenes with dextran. A reductive
amination step produced terpene end-modified dextran with 94 % of functionalization while
the esterification step produced three terpene grafted dextrans with a number of terpene units
per dextran of 1, 5 and 10. The amphiphilic renewable grafted polymers were tested as
emulsifiers for the stabilization of liquid miniemulsion of terpene droplets dispersed in an
aqueous phase. The average hydrodynamic diameter of the stable droplets was observed at ca.
330 nm.
