The hybridization of poly (ethylene terephthalate)(PET) with montmorillonite (Mont) clay was investigated using anchor monomers, i.e., hydroxyethyl isonicotinamide (HENA) or hydroxypentyltrimethylammonium iodide (HPTA), which have cationic substituents to adsorb onto clay surfaces and a hydroxyethyl moiety (-CH2CH2OH) to react with the polymer chain terminal of PET. The condensation of the mixtures of the intercalation compounds, bis (2-hydroxyethyl) terephthalate (BHET) and HENA/Mont or HPTA/Mont, led to a homogenous and transparent PET hybrid in which the Mont clay particles were scattered homogenously. The HPTA/Mont hybrid films copolymerized with BHET exhibited a dramatic improvement in such characteristics as tensile strength and optical transparency.
