An electrically conductive resin composition comprising:

Electrically conductive resin composition

An electrically conductive thermoplastic resin and coating composition comprising a diphosphonic acid derivative having the formula: ##STR1## wherein R represents an alkyl or aryl group and M.sup.1 to M.sup.4 independently represent hydrogen or a cation. The electrically conductive thermoplastic resin composition has excellent electrical conductivity and retains the electrical conductivity for extended periods without using expensive noble metals. Furthermore, the electrically conductive coating composition provides an excellent electrical conductivity and shielding property retention without using expensive noble metals.

Electrically conductive thermoplastic resin and coating compositions

The invention provides an improved method for producing a filler-loaded thermoplastic resin composite by mixing a thermoplastic resin with a filler, making it possible to be applied to molding machine such as extrusion and injection molding machines without the disadvantage of segregation between the resin and the filler otherwise inevitable leading to inferior uniformity of the shaped articles. The invention is characterized by the presence of a fibrillatable polytetrafluoroethylene during the mixing under mechanical shearing forces, wherein the thermoplastic resin is melted in one case and not melted in other case. The invention is also effective for shaping cellular foamed bodies of a filler-loaded thermoplastic resin with fine and uniform cellular structure.

Method for producing filler-loaded thermoplastic resin composite

An improved odorless polyolefin resin composition is proposed which is free from the problem of the generation of unpleasant odors unavoidable in the conventional polyolefin resin compositions filled with an inorganic filler due to the oxidative degradation of the ingredients. The deodorant effect in the inventive compositions is obtained by formulating limited amounts of a secondary alkane sulfonate having 12 to 20 carbon atoms per molecule and an organic nitrogen compound having at least one skeletal structure expressed by the formula ##STR1## in a molecule as exemplified by melamine and the like into a polyolefin resin-inorganic filler blend.
