    摘要: A composition comprising: a) one or more copolymers of i) one or more of one or more vinyl or vinylidene aromaticmonomers and/or (meth)acrylates; with ii) one or more unsaturated compounds containing one or more nucleophilic groups wherein the copolymer contains on average about 0.01 to about 5.0 percent by weight of nucleophilic groups based on the weight of the copolymer; b) one or more thermoplastic elastomer based polymers containing one or more nucleophilic groups; and c) one or more polymers having electrophilic groups; wherein the electrophilic groups have reacted with the nucleophilic groups and at least a portion of the one or more copolymers containing nucleophilic groups are bonded to at least a portion of the one or more thermoplastic elastomers containing one or more nucleophilic groups by at least a portion of the one or more polymers having electrophilic groups.

    摘要: Provided is a method for manufacturing a methacrylic resin composition having excellent surface processability and displaying excellent preservability of formed surface processing. A method for manufacturing a methacrylic resin composition, wherein the methacrylic resin composition comprises two or more types of methacrylic resins that each have a structural unit (X) having the same type of cyclic structure-containing main chain, the methacrylic resin composition has a Vicat softening temperature of 120° C. to 160° C., methanol-soluble content is contained in an amount of 5 mass % or less relative to 100 mass %, in total, of the methanol-soluble content and methanol-insoluble content, comprising mixing a low molecular weight component and a high molecular weight component.

    摘要: A resin composition comprises: a vinyl-containing polyphenylene ether resin, a bis(vinylphenyl)ethane and a modification of divinylbenzene. The resin composition may be used to make various articles, such as a prepreg, a resin film, a laminate or a printed circuit board, and achieves improvements in at least one of the properties including dielectric constant, dissipation factor, copper foil peeling strength, glass transition temperature, ratio of thermal expansion, thermal expansion coefficient, precipitation property of varnish, solder dipping thermal resistance, solder floating thermal resistance of multi-layer board, reflow thermal resistance of multi-layer board and T300 thermal resistance.
