A resin composition, a copper-clad laminate using the same, and a printed circuit board using the same are introduced. The resin composition comprises a specific phosphorus-containing salt and a prepolymer of vinyl-containing polyphenylene ether. The resin composition features specific ingredients and proportion to thereby achieve satisfactory properties of prepreg made from the resin composition, and attain satisfactory laminate properties, such as high degree of heat resistance and satisfactory dielectric properties, and thus is suitable for producing a prepreg or a resin film to thereby be applicable to copper-clad laminates and printed circuit boards.

摘要:
A polyester-based fiber for artificial hair of the present invention is a polyester-based fiber for artificial hair formed of a polyester resin composition. The polyester resin composition contains 5 to 40 parts by weight of a brominated epoxy flame retardant and 0.05 to 5 parts by weight of an acidic compound with respect to 100 parts by weight of a polyester resin. The polyester resin is one or more kind of resin selected from the group consisting of polyalkylene terephthalate and copolymerized polyester containing polyalkylene terephthalate as a main component. The acidic compound is an acidic phosphorus-based compound having a pH of 3.5 or less. A hair ornament product of the present invention contains the polyester-based fiber for artificial hair.
摘要:
A curable composition comprises (a) a mercapto-functional siloxane; (b) a siloxane comprising unsaturated functional groups; (c) a photoinitiator; and (d) an antioxidant compound. In one embodiment, the antioxidant is chosen from a hindered phenolic compound. The curable compositions can be utilized to form a cured article, which may be useful in a variety of applications including, but not limited to, optical applications. The cured articles from the cured compositions may exhibit good physical properties including, for example, high refractive index. The articles may also exhibit good thermal stability.
摘要:
To provide a technique in which a phosphorus compound does not inhibit curing of an addition reaction type silicone-based composition even though the addition reaction type silicone-based composition is in contact with a resin molded product containing the phosphorus compound. An integrated molded product including a thermoplastic resin molded product containing a phosphorus compound, an addition reaction type silicone-based composition, and a member, in which: the thermoplastic resin molded product is in contact with the addition reaction type silicone-based composition; and a pentavalent phosphorus compound is used as the phosphorus compound. The thermoplastic resin molded product preferably contains a polybutylene terephthalate resin in light of heat resistance.
