( ) ed in original clay a littlewhile could be well intercalated in organically modified clay T hepresence. - . of the alkyl ammonium cations in the galleries of organo clay rendered thehydrophilic clay organic T he role of alkyl ammonium cations was to lower the surface energy of the inorganic clay and im- prove its wetting characteristic with poly vinyl chloride( ) . Mechanical properties testing showed that the nanocomposites were superior to poly (vinyl chloride) in terms of impact strength, heat dis- tortion temperature, solvent transformation resistance without sacrificing its tensile strength.
