Provided is a rubber-containing graft polymer capable of reducing wet heat aging of a shaped article while improving the strength developing property of a thermoplastic resin. In the rubber-containing graft polymer of the present invention, a content of components having a weight-average molecular weight of 800,000 or more is 1% by mass or more with respect to an organic solvent-soluble fraction (100% by mass) of the rubber-containing graft polymer, and a phosphorus content in the rubber-containing graft polymer is 3 to 30 mmol/kg.

Rubber-containing graft polymer, resin composition containing rubber-containing graft polymer, and shaped article of same

An object of the present invention is to provide a polyorganosiloxane-containing graft copolymer powder capable of providing a resin composition and a molded article which are excellent in balance between colorability and mechanical properties such as impact resistance. The polyorganosiloxane-containing graft copolymer powder according to the present invention is a graft copolymer powder obtained by graft-polymerizing a mixture (B) of a vinyl monomer (b1) having an epoxy group and another vinyl monomer (b2) to a rubber (A) containing a polyorganosiloxane, wherein the content of the polyorganosiloxane (A1) contained in the rubber (A) is 12 to 50% by mass, the mass average particle diameter of the polyorganosiloxane-containing graft copolymer powder is 300 to 2000 nm, and the epoxy equivalent of the polyorganosiloxane-containing graft copolymer powder is 2500 to 7800 g/eq.

Polyorganosiloxane-containing graft copolymer powder, and resin composition using the same, and molded article formed of the same

A (meth)acrylate resin material comprising a polymer (A1) having constituent units (a1) derived from a compound represented by formula (1) and constituent units (a2) derived from methyl methacrylate, and an acid (B) and/or a nucleating agent (C). In the formula, Ar represents an aryl group, and the aromatic ring in Ar is directly bonded to the ester end in formula (1). 

(Meth)acrylate resin material, surface hardness enhancer, polycarbonate resin composition, and molded article

To enhance adhesion between a resin and a glass filler and at the same time to disperse a rubber in the resin to thereby improve mechanical properties of a molded body. Provided is a resin composition containing an engineering plastic (A), a glass filler (B) and a rubber-containing graft polymer (C), wherein a ratio of an acrylonitrile-derived component in a chloroform-soluble component of the resin composition is not more than 2.0 mass %, a content of a fatty acid in 100 parts by mass of the resin composition is not more than 0.03 parts by mass, a total content of calcium and magnesium in 100 parts by mass of a dry sample of the resin composition extracted with chloroform is not more than 0.0008 parts by mass, and a content of aluminum is not more than 0.0008 parts by mass. Also provided is a resin composition further containing a salt (D) of an alkali metal and a strong acid. The engineering plastic (A) is preferably an aromatic polycarbonate resin. Also provided is a molded body obtained by molding the resin composition.

Resin composition and molded body thereof

This vinyl polymer powder, which contains a vinyl polymer, has a glass transition temperature of at least 0&#xb0; C. (where if there are a plurality of glass transition points, all of the glass transition temperatures are at least 0&#xb0; C.), has no greater than 350 ppm of the total content of magnesium ions, calcium ions, aluminum ions, barium ions, and zinc ions, has no greater than 100 ppm of the content of ammonium ions, has an acid number of no greater than 2.5 mgKOH/g, and has a bulk density of 0.10-0.60 g/cm.

Vinyl polymer powder, thermoplastic resin composition, and molded body thereof

A polycarbonate resin composition and a molded article thereof are described, which have good flame retardance and high thermal stability when molded under high temperature. The resin composition contains a resin modifier (B) containing a tetrafluoroethylene-based polymer (p1) and a vinyl polymer (p2) other than the polymer (p1). The resin modifier (B) is obtained by using an alkaline (earth) metal salt other than a sulfate salt to coagulate a latex containing the polymer (p1) and the polymer (p2). The polymer (p2) is formed by performing polymerization on a vinyl monomer (X) containing at least 20 mass % of an aromatic vinyl monomer (x1) in the presence of at least one emulsifier selected from a phosphoric acid-based emulsifier, a carboxylic acid-based emulsifier, and a nonionic emulsifier.
