Method for producing dicyclopentadiene-modified phenolic resin

A method for producing a dicyclopentadiene-modified phenolic resin. The method including reusing a fluorine-based ion-exchange resin as a catalyst in a reaction between a phenol and a dicyclopentadiene, the fluorine-based ion-exchange resin having been used as a catalyst when a phenol and a dicyclopentadiene are allowed to react with each other to produce a first dicyclopentadiene-modified phenolic resin. ...

Polyamide acid composition and polyimide composition

A polyamide acid composition and a polyimide composition are obtained from a tetracarboxylic acid compound containing an aromatic tetracarboxylic acid compound having a naphthalene skeleton and a diamine compound containing an aromatic diamine compound having a biphenyl skeleton.. . ... Jfe Chemical Corporation

Amorphous carbon particles

A method for producing amorphous carbon particles comprising includes adding and mixing graphite particles into a precursor of amorphous carbon and then cross-linking the precursor of amorphous carbon to obtain a first cross-linked product, or cross-linking a precursor of amorphous carbon and then adding and mixing graphite particles into the cross-linked precursor of amorphous carbon to obtain a second cross-linked product. Infusibility is imparted to the first or second cross-linked product to obtain an infusibilized product to which infusibility has been imparted. ... Jfe Chemical Corporation

Poly(amic acid) composition and polyimide composition

There is provided a polyimide composition that is useful for electronic substrate materials, retains high heat resistance and mechanical strength intrinsic to polyimides, and has a lower dielectric constant and dielectric loss tangent. A polyimide composition for use in electronic substrate materials, containing a polyimide produced by polymerization between a diamine component containing 5-(4-aminophenoxy)-3-[4-(4-aminophenoxy)phenyl]-1,1,3-trimethylindan and an acid component containing 3,3′,4,4′-biphenyltetracarboxylic acid dianhydride.. ...
