There is provided a composition of melt processible fluoropolymer and inorganic fine particles of average particle size 1 mm or less dispersed in said fluoropolymer, said composition being obtained by melt-mixing said melt processible fluoropolymer and aggregated said inorganic fine particles, said aggregated inorganic fine particles being obtained by drying a mixed solution of inorganic fine particles and an inorganic salt to obtain a solid material, removing the inorganic salt from this solid material using a solvent, and then drying at a temperature where surface fusion between the inorganic fine particles does not occur, whereby said aggregates are the result of the mutual cohesive force of the inorganic fine particles, which has good physical properties and dimensional stability compared to the melt processible fluoropolymer alone.
Disclosed is a fluororesin laminate substrate comprising a plurality of substrates provided with a circuit pattern, and an adhesive layer for bonding the substrates. This fluororesin laminate substrate is characterized in that the substrates are made of a prepreg formed by impregnating a reinforced fiber sheet with a first fluororesin mixture, and the adhesive layer is composed of a film of a second fluororesin mixture. The fluororesin laminate substrate is further characterized in that the second fluororesin mixture is a fluororesin mixture having thermofusion property whose melting point is lower than that of the first fluororesin mixture.
A composition having excellent resistance to chemical permeation, comprising (A) a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, (B) a melt-flowable polytetrafluoroethylene directly obtained by the polymerization of tetrafluoroethylene, and (C) a polytetrafluoroethylene with a low molecular weight obtained by the radiolysis of a non-melt flowable polytetrafluoroethylene with a high molecular weight; the weight ratio of A/(B + C) is 80/20 to 30/70; and the weight ratio of (A + B)/C is 99.99/0.01 to 90/10.
The present invention provides a polymer composition wherein inorganic particles are uniformly dispersed at the nano level in the polymer without having said inorganic particles being surface-treated. It further provides a method for manufacturing a polymer composition wherein a co-aggregate which is obtained by uniformly mixing polymer dispersion with an inorganic particle colloidal solution and co-aggregating the polymer primary particles and inorganic particles which are heterogeneous particles, is separated from the solvent and dried so that the inorganic particles are uniformly dispersed at the nano level in the polymer; and the polymer composition which is obtained by said method.

COPPER-CLAD LAMINATE, PRINTED WIRING BOARD, MULTILAYER PRINTED WIRING BOARD, AND METHODS FOR PRODUCING THOSE
Disclosed is a copper-clad laminate wherein the copper foil adhesion strength (copper foil peeling strength) is greatly improved without subjecting the copper foil surface to a roughening treatment or a blackening treatment. This copper-clad laminate can be adequately used in a high frequency region. Specifically disclosed is a copper-clad laminate (101) for single-sided printed wiring boards, which is obtained by bonding a copper foil (4) onto one surface of an insulating substrate (2), which is composed of a fluoroplastic prepreg (2A), via a composite film (3) of LCP and PFA. The copper foil (4) is a rolled copper foil having a smooth surface without being subjected to a roughening treatment or a blackening treatment on both sides. The insulating substrate (2) and the copper foil (4) are bonded with each other via the composite film (3) by being fired and pressed at a temperature higher than the melting point of PFA by 5-40˚C and lower than the melting point of LCP.

A binder for a battery electrode comprising a vinyl fluoride-based copolymer. The vinyl fluoride-based copolymer preferably comprises about 25 to about 85 mol% vinyl fluoride and about 75 to about 15 mol% of at least one other fluorine-containing monomer. In a preferred embodiment, the binder comprises a mixture of at least two types of vinyl fluoride-based copolymers. In another embodiment the binder comprises a vinyl fluoride-based copolymer and at least one other fluorine-based polymer. The binder can be dispersed in water or organic solvent to form a paste for binding electrode materials to current collectors for battery electrode fabrication. Battery electrodes with improved adhesion strength and electrochemical stability result.
