摘要:
A particle with a rough surface for plating or vapor deposition which has been formed from a base (A) having first functional groups on the surface thereof and particles (B) having on the surface thereof second functional groups reactive with the first functional groups and having an average particle diameter which is smaller than the diameter of the base (A) and not smaller than 0.1 μm, by uniting the base (A) with the particles (B) through chemical bonds between the first functional groups and the second functional groups, wherein the base (A) has at least two projecting parts on the surface thereof. In this particle, the base has been tenaciously bonded to the protruding particles. Because of this, even when the protruding particles used have a size not smaller than the given size, the particle with a rough surface can secure a surface area while maintaining a thickness of a conductive coating film. As a result, the particle can have high conductivity.
摘要:
A particle having a rough surface and obtained from a particle (A) having grafted on the surface thereof a polymer having first functional groups and particles (B) having grafted on the surface thereof a polymer having second functional groups reactive with the first functional groups, by uniting the particle (A) with the particles (B) through chemical bonds between the first functional groups and the second functional groups. In this particle with a rough surface, the core particle has been tenaciously bonded to the protruding particles. Because of this, even when the protruding particles have an increased particle diameter, the protruding particles can be prevented from readily shedding from the core particle.
摘要:
Disclosed is a resin composition wherein dispersibility of a modifying agent such as an inorganic substance is improved. The acid resistance of this resin composition is not deteriorated even when a modifying agent is blended therein. Specifically, the resin composition includes a base material having a cyano group-containing organic layer and an organic resin. This resin composition is extremely excellent in acid resistance when compared with organic resins which use a base material having an organic layer not containing a cyano group.

Disclosed is an inorganic-organic composite flame retardant composition which contains an inorganic hydroxide having a polymer layer and an organic resin. The polymer layer is formed through graft polymerization and has an average thickness of not less than 3 nm. When a shaped article is formed by using such a composition, the shaped article can have a sufficient flame retardance while being prevented from decrease in acid resistance, increase in dielectric constant or the like.
摘要:
A filler for substrates which comprises an inorganic substance and a carbodiimide-group-containing organic layer chemically bonded to the surface of the inorganic substance. Examples of the carbodiimide-group-containing organic layer include a layer comprising a carbodiimide-group-containing compound represented by either of the following formulae. Due to the constitution, the filler for substrates can be highly dispersed in a resin for substrates even when added in a high proportion and can give a substrate inhibited from deteriorating in electrical properties, mechanical properties, etc. (X1)m—Z-[A-(R1—N═C═N)n—R1—NCO]1 (1) (X1)m—Z-[A-(R1—N═C═N)n—R1-A-Z—(X2)3]1 (2) [R1 represents a residue of an isocyanate compound; X′ and X2 each independently represents hydrogen, halogeno, etc.; Z′s each independently represents silicon or titanium; A represents an organic group having a valence of 2 or higher containing a bond derived from an isocyanate group; m and 1 each is an integer of 1-3, provided that m+1=4; and n is an integer of 1-100.]
