Provided is a method for producing resin particles by melt-kneading with a non-water-soluble resin in a wide range of melt-kneading temperature according to the melting point or glass transition temperature of the resin. This production method includes melt-kneading a water-soluble matrix, containing a modified polyvinyl alcohol-based resin, and a non-water-soluble resin to form a pre-molded article in which the non-water-soluble resin is dispersed in particulate; and bringing the pre-molded article into contact with an aqueous solvent to elute the matrix. The modified polyvinyl alcohol-based resin contains in a side chain thereof an alkyl group including at least one hydroxyl group (for example, a 1,2-dihydroxyalkyl group).

Method for producing resin particles

Provided are: a water-soluble matrix whose melt-kneading temperature can be adjusted according to the melting point or glass transition temperature of a resin; a pre-molded article in which resin particles are dispersed in the water-soluble matrix; and a method for producing resin particles.

A method for manufacturing a transparent gas barrier film for an organic electroluminescence element having a substrate with a gas barrier layer thereon. The gas barrier layer is formed on the substrate by plasma CVD using an organic silicon compound as a raw material gas and an oxygen gas as a decomposition gas. Formation of the gas barrier layer is carried out so that a carbon content of the gas barrier layer in the thickness direction repeatedly changes more than two times from high value, via intermediate value, low value and intermediate value, to high value.

The present invention is directed to a composite comprising a resin element comprising a resin composition and a vulcanized rubber element formed by vulcanizing an unvulcanized rubber, wherein the resin composition comprises a resin, a vulcanization-activating agent for improving adhesiveness of the resin to a rubber, and a stabilizer, and the resin composition and the vulcanized rubber are directly joined together.

Resin composition and composite using the composition and production process thereof

A resin composition comprises a resin, a vulcanization-activating agent, and a stabilizer. The vulcanization-activating agent may be a compound having a plurality of polymerizable unsaturated bonds (e.g., a compound having a plurality of (meth)acryloyl groups). The stabilizer may be an antioxidant, or a light stabilizer (particularly, a stabilizer is capable of capturing a radical). Use of the resin composition as a resin material ensures to directly join between a resin and a rubber certainly and firmly. The proportion of the vulcanization-activating agent may be about 0.1 to 10 parts by weight relative to 100 parts by weight of the resin. The proportion of the stabilizer may be about 0.01 to 5 parts by weight relative to 100 parts by weight of the resin. The present invention provides a resin composition excellent in adhesiveness to a rubber.

The polyamide-series resin may comprise a polyamide-series resin having a free amino group in a concentration of not less than about 10 mmol/kg. The molded composite article is producible, for example, by heating at least one of the polyamide-series resin and the thermoplastic polyurethane-series resin to bond the former to the latter. Thus obtained molded composite article is suitable for a member of a shoe and an industrial roll. In such a process, the polyamide-series resin member and the thermoplastic polyurethane-series resin member both of which are different in nature from each other can be directly and firmly bonded together.
