Novel blends made of ionic naphthalene thermotropic polymer and poly(ethylene terephthalate)

Effect of Nanoclay Incorporation on the Thermal Properties of Poly(ethylene terephthalate)/Liquid Crystal Polymer Blends

“…Considering the variation of T c with f, the activation energy (absolute value of DE) was estimated from the slopes [represented by Equation (8)(9)(10)] of the least square lines. Figure 13 illustrates the least square plots representing the Augis-Bennett, Kissinger and Takhor methods.…”

“…[5] For this reason, many literatures are available on PET/LCP blends. [6][7][8][9][10][11] They used different types of LCP such as Vectra A950, poly[(ethylene oxide)-graft-(sebacic acid/4,4'-dihydroxybiphenyl)] (PE-g-SBH), poly(ethylene 2,6-napthalate) (PEN), para-hydroxybenzoic acid/PET (PHB60-PET40), hydroxybenzoic acid/PET (HBA73-PET40), p-amino benzoic acid/PET (ABA30/PET), Rodrun LC5000 and also selfsynthesised phosphorus-containing LCP to prepare blends. Recently, researchers also used compatibilisers such as Lotader AX8900, [9] polycarbonate [PC], [7] poly(dihydroxyether), [10] etc., to compatibilise PET/Vectra A950 blends.…”

“…In most of the cases if there is a good miscibility between PET and LCP, the mechanical properties of the blend such as modulus and strength increases. [7,8,10,11] Recently, Chang et al [12] prepared blend of thermotropic LCP and PBT/organoclay composite and reported about the texture and enhanced tensile properties for the blend compared to the composite. Tang et al studied the effect of incorporation of thermotropic LCP on the rheological behaviour of PE/organoclay composites by capillary rheometry experiments.…”
