摘要:
In the manufacture of prepreg using various types of resin varnish having different properties, prepreg having good appearance and desired properties is manufactured without decreasing productivity. A prepreg manufacturing apparatus is able to perform, in a base material feeding path, immersing a base material in resin varnish in a tray, scraping off the excess resin varnish on the base material with scraping rollers which are provided above the tray, and thereafter drying the base material with a drying device. The prepreg manufacturing apparatus is configured such that, on the base material feeding path, the distance from the liquid surface of the resin varnish in the tray to the scraping rollers and the distance from the scraping rollers to the drying device are adjustable.

It is an object of the present invention to provide a resin composition which can realize a printed wired board having not only low water-absorbing property but also excellent heat resistance after moisture absorption, flame retardancy, and solvent solubility. It is another object of the present invention to provide a prepreg and a monolayer or laminate which use the resin composition, and a metal foil clad laminate and a printed wired board which use the prepreg. A resin composition of the present invention contains one or two or more cyanate ester compounds (A) represented by the following formula (1) and an epoxy resin (B): wherein R1, R2, R3, and R4 represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and may be the same or different from each other; and n represents an integer of 1 to 50.

摘要:
The present invention is a cyanate ester compound represented by the following formula (1): wherein Ar represents an aromatic ring; R1 each independently represents a hydrogen atom, an alkyl group, or an aryl group; n each independently represents an integer of 1 to 3; m+n is the same as the total number of hydrogen atoms in a monovalent aromatic group containing the aromatic ring and the hydrogen atoms; R2 represents a hydrogen atom (excluding a case where Ar represents a benzene ring; n each represents 1; R1 represents a hydrogen atom; m each represents 4, and a cyanate group is bonded to the benzene ring in the 4-position relative to an adamantyl group), or an alkyl group having 1 to 4 carbon atoms; and R3 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
摘要:
A method for efficiently producing a cyanogen halide with suppressed side effects, and a method for producing a high-purity cyanate ester compound at a high yield includes contacting a halogen molecule with an aqueous solution containing hydrogen cyanide and/or a metal cyanide, so that the hydrogen cyanide and/or the metal cyanide is allowed to react with the halogen molecule in the reaction solution to obtain the cyanogen halide, wherein more than 1 mole of the hydrogen cyanide or the metal cyanide is used based on 1 mole of the halogen molecule, and when an amount of substance of an unreacted hydrogen cyanide or an unreacted metal cyanide is defined as mole (A) and an amount of substance of the generated cyanogen halide is defined as mole (B), the reaction is terminated in a state in which (A):(A)+(B) is between 0.00009:1 and 0.2:1.
