no. 1 approach

[0081] In the first embodiment of the carbon cluster-containing composition of the present invention (hereinafter, sometimes referred to as "the composition of this embodiment"), the carbon cluster (A), the first solvent (B1), the second solvent (B2), an ethylenically unsaturated group-containing monomer (C), and a resin (D). Among them, the ethylenically unsaturated group-containing monomer (C) is a carboxyl group-containing ethylenically unsaturated compound (m-2). The resin (D) is an epoxy group-containing copolymer (P1) or an epoxy resin (P3).

[0082] As the carbon cluster (A), any one of the above specific examples or a mixture thereof can be used. As the first solvent (B1) used in the present embodiment, any one of the specific examples of the above-mentioned first solvent (B1) or a mixed solvent thereof can be used. Among them, preferably toluene, benzene, xylene, ethylbenzene, trimethylbenzene, chlorobenzene, dichlorobenzene, or their mixed solvents, more preferably...

[0141] In the second embodiment of the carbon cluster-containing composition of the present invention (hereinafter, sometimes referred to as "the composition of this embodiment"), the carbon cluster (A), the first solvent (B1), the second solvent (B2), an ethylenically unsaturated group-containing monomer (C), and a resin (D). Among them, the ethylenically unsaturated group-containing monomer (C) is an epoxy group-containing ethylenically unsaturated compound (m-1). The resin (D) is a carboxyl group-containing copolymer (P2) or a carboxyl group-containing resin (P4).

[0142] For the carbon cluster (A), the first solvent (B1), and the second solvent (B2), the same ones as those in the first embodiment can be used.

[0143] The carboxyl group-containing copolymer (P2) or the carboxyl group-containing resin (P4) is ring-openingly added to the epoxy group of the epoxy group-containing ethylenically unsaturated compound (m-1) to generate a hydroxyl group. It is preferable to fur...

no. 3 approach

[0169] In the third embodiment of the carbon cluster-containing composition of the present invention (hereinafter, sometimes referred to as "the composition of this embodiment"), the carbon cluster (A), the first solvent (B1), the second solvent (B2), and resin (D). Among them, the resin (D) is an ethylenically unsaturated resin (A1) or an ethylenically unsaturated resin (A3).

[0170] As the carbon cluster (A), the first solvent (B1), and the second solvent (B2), those used in the first embodiment can be used in the same manner.

[0171] The ethylenically unsaturated resin (A1) contains a monomer composed of a carboxyl group-containing ethylenically unsaturated compound (m-2) and, if necessary, a polybasic acid anhydride (d), and an epoxy group-containing copolymer (P1) The resin (D) precursor is obtained. In addition, as the ethylenically unsaturated resin (A3), a monomer composed of a carboxyl group-containing ethylenically unsaturated compound (m-2) and, if necessary, a ...

Abstract

The present invention provides a composition in which carbon clusters are uniformly dispersed. A carbon cluster-containing composition according to the present invention contains carbon clusters (A), a first solvent (B1), a second solvent (B2), and at least one substance that is selected from the group consisting of ethylenically unsaturated group-containing monomers (C) and resins (D). The first solvent (B1) is composed of at least one solvent that is selected from the group consisting of aromatic solvents and halogen-containing solvents; and the second solvent (B2) is composed of a solvent other than aromatic solvents and halogen-containing solvents.

Description

technical field [0001] The present invention relates to a composition containing carbon clusters and a method for producing the same. [0002] This application claims priority based on Japanese Patent Application No. 2018-222729 filed in Japan on November 28, 2018, and the content thereof is incorporated herein. Background technique [0003] In recent years, many studies have been conducted on the production of resins imparted with properties such as heat resistance by adding fullerenes. For example, non-patent literature 1 discloses that containing fullerene (C 60 ) polypropylene or high density polyethylene resin composition. However, in order to uniformly disperse the fullerenes, it is necessary to mix the resins in a melted state at a temperature close to 200° C. for a long time. In addition, dispersion sometimes becomes insufficient. Therefore, Patent Document 1 discloses a resin composition containing a long-chain alkyl etherified fullerene derivative having improv...
