“…These diols have attracted considerable attention in the field of materials science 6–11. These sugar‐based stereoisomeric diols represent highly useful diol components for the syntheses of various polymers such as polyesters,12–18 polyamides,19, 20 polyethersulfones,21, 22 poly(ester amide)s,23–26 poly(ester imide)s,26–28 polyurethanes,29 or polycarbonates 29–36. As an extension of the series of our studies on polymers syntheses based on the diols 1a–c, we describe in this paper synthesis and characterization of poly (ether ketone)s (PEKs), which can substitute the conventional ones based on diphenols.…”

A new class of poly(ether ketone)s (PEKs) is prepared by polycondensation of various diols produced from biomass and various difl uoro aromatics. After optimization of the reaction conditions, polycondensation of isosorbide and 4,4 ′ -difl uorodiphenylketone (2a) gives PEK1 with a high yield, moderate viscosity (0.31 dL g − 1 ), and a glass-transition temperature ( T g ) of 170 ° C. The optimum conditions are applied to the synthesis of a series of PEKs (PEK 2-9) from difl uoro agents and sugar diols. The polycondensation of isomannide (1b) with 1,4-di(p-fl uorobenzoyl)benzene (2b) gives the best results with an inherent viscosity of 0.52 dL g − 1 and the mass spectrum shows an abundance of cyclic structures. Similar conditions are used for the preparation of high-molarmass copoly(ether ketone)s from a stoechiometric mixture of isosorbide/bisphenol-A.

“…There are several polymers that undergo decomposition before melting or glass transition. 71,72 It is expected that different polymorphs of the monomer and polymer will have different mechanical properties, in view of the difference in their packing and intermolecular interactions. We studied the mechanical properties of these crystals by nanoindentation.…”
