    Abstract: Disclosed is a fine polymer particle production method comprising producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.

    Abstract: A production method of polyvinylidene fluoride resin particles comprising: (Process al) a process to precipitate the polyvinylidene fluoride resin particles by adding a 100 mass% solution in total consisting of 75 to 99 mass% organic solvent, 1 to 25 mass% water and 0.5 to 15 mass% polyvinylidene fluoride resin to a poor solvent of the polyvinylidene fluoride resin; or (Process a2) a process to precipitate polyvinylidene fluoride resin particles by performing a flash-crystallization of the solution. With such a configuration, PVDF resin particles can be industrially produced by simple operations without using surfactant agent.

    Abstract: Provided is a prepreg for obtaining a fiber-reinforced composite material which combines stable impact resistance and interlaminar toughness with compressive strength under wet heat conditions. The prepreg comprises an epoxy resin, reinforcing fibers, and polymer particles [C] which are insoluble in the epoxy resin and are either [Cx] or [Cy], wherein 90% or more of [C] are present in the range of from one or each surface of the prepreg to a depth corresponding to 20% of the thickness of the prepreg. [Cx] Polymer particles giving a particle diameter distribution chart (x-i) which has at least two peaks and (x-ii) in which the particle diameter ratio between the two highest peaks is in the range of 1.5-7 and (x-iii) in which the peak, of the two highest peaks, that is located on the larger-particle-diameter side has a half-value width in the range of 1.1-3. [Cy] Polymer particles (y-i) which have an average particle diameter which is 1-18 µm or is larger than 12 µm but not larger than 50 µm, (y-ii) which have a degree of sphericity of 90-100, and (y-iii) which have a glass transition temperature of 80-155ºC.

    Abstract: Disclosed is a method for producing polymer fine particles, which is characterized in that after forming an emulsion in a system obtained by dissolving and mixing a polymer A, a polymer B and an organic solvent, and consisting of two separate phases, namely a solution phase mainly composed of the polymer A and a solution phase mainly composed of the polymer B, a poor solvent of the polymer A is brought into contact with the emulsion, thereby precipitating the polymer A. By this method, polymer fine particles having a narrow particle size distribution can be easily synthesized. Consequently, the method can be effectively applied to production of polymers having high heat resistance which have been difficult to produce.
