A composite particle that can be easily converted to cured particle or half cured particle by the use of carbodiimide resin without changing of the configuration of matrix particle of, for example a thermoplastic resin, excelling in mechanical and functional characteristics by virtue of the reaction capability inherently possessed by a carbodiimide group. In particular, a composite particle comprising matrix particle (A) having a functional group capable of reacting with a carbodiimide group and carbodiimide resin (B), characterized in that the functional group of the matrix particle (A) couples with the carbodiimide group of the carbodiimide resin (B) and that the composite particle is provided with an outer shell layer of carbodiimide resin (B) having an average thickness diameter (L), defined by the following formula [1], ranging from 0.01 to 20 μm: L=(L2−L1)/2 [1] wherein L1 represents the average diameter of matrix particle, and L2 represents the average diameter of composite particle.

Flaky particles which are produced through easy conversion from mother particles by using an organic compound other than monomers having double bonds as the hardening and crosslinking agent and to which at least one mechanical or functional characteristic selected from among reactivity, close adhesion, and tackiness is imparted by the presence of part of the unreacted reactive groups of the organic compound inside and on the particles; and a process for the production of the flaky particles. More specifically, flaky particles composed of mother particles (A) having functional groups and an organic compound (B) which has groups reactive with the functional groups of the particles (A) and is soluble in a solvent, characterized in that at least part of the functional groups of the mother particles (A) and at least part of the reactive groups of the organic compound (B) react with each other to form crosslinks.

Conductive particles each includes a polymer base particle and a conductive layer coating the polymer base particle. Let the compressive elastic deformation characteristic KX of one conductive particle when the displacement of particle diameter of the conductive particles is X % be defined by the following formula: KX=(3/√2)·(SX−3/2)·(R−1/2)·FX. FX is the load (N) necessary for X % displacement of the conductive particles. SX is the compressive deformation amount (mm) upon X % displacement of the conductive particles. R is the particle radius (mm) of the conductive particles. The compressive elastic deformation characteristic K50 when the displacement of particle diameter of the conductive particles is 50% is 100 to 50000 N/mm2 at 20° C., and the recovery factor of particle diameter of the conductive particles when the displacement of particle diameter of the conductive particles is 50% is not less than 30% at 20° C.
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.

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.

Oval-spherical organic polymer panicles having ionic functional groups, which have each one continuous curved surface whose aspect ratio calculated by the formula: aspect ratio (P1)=major axis (L1)/minor axis (D1), wherein the major axis (L1) and minor axis (D1) are those of a projection two-dimensional drawing obtained by light irradiation in the direction orthogonal to the direction of major axis of the panicle, satisfies the relationship (P1)≧1.8. The obtained particles excel in optical properties, such as light scattering and light focusing, and frictional properties, such as sliding characteristic.

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.
