The present invention provides a thermoplastic resin formed product containing glass fiber having a length of at least 0.4 mm in an amount within a range of from 5 to 60 wt. % and at least a kind of conductive material in an amount within a range satisfying the following formula (1): ##EQU1## where, W.sub.k is the content in weight of each conductive material (%), E.sub.k is volume resistivity of each conductive material (.OMEGA..multidot.cm), and n is the number of kinds of conductive material. Further, the present invention provides also a method of manufacturing a thermoplastic resin formed product, comprising the step of forming a thermoplastic resin containing glass fiber having a weight average fiber length of at least 1 mm in an amount within a range of from 10 to 90 wt. %, in which the glass fiber is substantially impregnated with the resin, and a material containing at least one conductive material, while mixing the same or after mixing the same.

Glass long fiber-reinforced thermoplastic resin form having conductivity

Copolymer of maleic anhydride and the polymerizable component of naphtha oil chiefly composed of indene and aromatic hydrocarbons having a reactive double bond, a resin modifier containing said copolymer as an effective ingredient, a dispersant containing a salt of the sulfonation product of said copolymer, an esterified product of said copolymer, and preferred processes for producing these products.

Copolymer of polymerizable components in naphtha oil and maleic

The novel imidated copolymer of indene or the polymerizable component of naphtha oil and maleimide and, if necessary, maleic anhydride is useful as a resin improver and a compatibilizing agent for the purpose of improving heat resistance and mechanical properties. Another novel imidated copolymer prepared by applying copolymerization of other polymerizable component to the polymerization process is useful as a resin improver and a compatibilizing agent in which, in addition to the above characteristic properties, melting temperature can be designed to a given level.

Imidated copolymers and uses thereof

Dispersant and cement admixture

A catalyst comprising an inert support that carries on it vanadium oxide, sodium oxide and molybdenum oxide in predetermined amounts, at least one additional component in a predetermined amount which is selected from among chromium oxide, manganese oxide, niobium oxide and titanium oxide is capable of producing pyromellitic dianhydride in high yield from inexpensive durene over a broad optimal temperature range while suppressing the generation of heat in the catalyst bed.

Catalyst used in a process for producing pyromellitic dianhydride

A catalyst in the form of a honeycomb structured cordierite carrier having platinum supported in a loading weight of at least 0.20 mg per square centimeter of the apparent outer surface area of the catalyst is effective in a process for oxidizing CO in exhaust gas from a sintering furance wherein it maintains high CO oxidiation efficiency for a longer period of time, requiring less frequently regeneration and less power consumption.
