Abstract

This study present two series of polyetherurethanes (PEUs) based on cellulose derivatives. First series was synthesized from polytetramethylene ether glycol (PTMEG-2000), as macrodiol, 1,6-hexamethylene diisocyanate (HDI), 4,4’-methylene bis(cyclohexyl isocyanate) (HMDI), isophorone diisocyanate (IPDI), as aliphatic diisocyanate components and hydroxypropyl cellulose (HPC) as chain extender, by one-shot technique without catalyst. The second series differs from the first through diisocyanate components; these are 4,4’-diphenylmethane diisocyanate (MDI) and 2,4-toluene diisocyanate (TDI). The properties of these materials have been evaluated with respect to aliphatic or aromatic structure influence..
