Provided is a resin composition, comprising epoxy resin, oxydianiline type benzoxazine resin, styrene-maleic anhydride resin and tetra-phenol resin. The resin composition may be baked for producing products such as prepregs, resin films, resin-coated coppers, laminates and printed circuit boards, which satisfy one or more or all of desirable properties such as higher dimensional stability after a reflow process, better thermal resistance after horizontal black oxide process, low dielectric constant, low dissipation factor, high thermal resistance and flame retardancy.

Biologically activated ion-exchange polymer salts are made by exchanging biologically active ionic agents onto ion-exchange polymers. The activated polymers are uniquely surface active and stable to thermal degradation and chemical and other forms of decomposition. The activated ion-exchange polymer salts may be processed and combined with polymer precursors using novel methods and materials to produce stable, biologically activated polymer composites, including antimicrobial and antifouling polymer composites.

A method is used to provide an electrically-conductive polyaniline pattern by providing a uniform layer of a photocurable composition on a substrate. The photocurable composition comprises a water-soluble reactive polymer comprising (a) greater than 40 mol % of recurring units comprising sulfonic acid or sulfonate groups, and (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition. The photocurable composition is exposed to cause crosslinking via [2+2] photocycloaddition of the (b) recurring units, thereby forming a crosslinked polymer. Any remaining water-soluble reactive polymer is removed. The crosslinked polymer is contacted with an aniline reactive composition having aniline monomer and up to 0.5 molar of an aniline oxidizing agent, thereby forming an electrically-conductive polyaniline disposed either within, on top of, or both within and on top of, the crosslinked polymer.

Provided in the present invention are a halogen-free epoxy resin composition, prepreg and laminate using the same, the halogen-free epoxy resin composition comprising: (A) a halogen-free epoxy resin; (B) a crosslinking agent; and (C) a phosphorous-containing phenolic resin, the phosphorous-containing phenolic resin being formed by a synthesis of phenol and formaldehyde with dicyclopentadiene phenol, and being substituted by 9,10-dihydro-9-oxa-10-phosphapheanthrene-10-oxide or a derivative thereof. The prepreg and laminate prepared from the halogen-free epoxy resin composition have a high heat resistance, a low dielectric constant, a low dielectric loss factor and a low water absorption rate, and achieve halogen-free flame retardance.

A polyimide precursor solution contains a polyimide precursor, particles, and a water-based solvent that contains an amine compound (A), an organic solvent (B) other than the amine compound (A) and amide compounds, and water, in which a boiling point of the organic solvent (B) is higher than a boiling point of the amine compound (A), and is 200° C. or higher and 300° C. or lower.

A method for producing a resin particle dispersion includes: preparing a phase-inverted emulsion by phase inversion emulsification of a resin using an organic solvent and an aqueous medium; and removing the organic solvent from the phase-inverted emulsion by reduced pressure distillation. The reduced pressure distillation is performed using a reduced pressure distillation device including: a distillation tank that contains the phase-inverted emulsion; a heating unit that heats a tank wall of the distillation tank by causing a heated fluid to flow inside the heating unit; and an agitating unit disposed inside the distillation tank, the agitating unit including an agitating shaft and one or plural gutter-shaped agitation impellers that are attached to the agitating shaft, rotate to agitate the phase-inverted emulsion, and draw up the phase-inverted emulsion to form a liquid film of the phase-inverted emulsion on a heat transfer surface of the distillation tank in a portion above a liquid level of the phase-inverted emulsion. The aqueous medium is added to the phase-inverted emulsion contained in the distillation tank during the reduced pressure distillation.
