Problems solved by technology

2Functional epoxy (meth)acrylate has fluidity at room temperature and has good workability, but (meth)acryloyl groups exist only at both ends of the epoxy resin used as a raw material, so It is inferior to polyfunctional epoxy (meth)acrylate in terms of property and curing sensitivity, so in order to further increase the crosslink density of the cured product, it is necessary to prepare complicated compositions by using polyfunctional acrylic monomers and the like.
[0008] In other words, there has not been a method for producing a compound having an average of three or more compounds in one molecule that is rich in bands generated by active energy rays, free radicals, etc., by a one-stage reaction. Curable or thermosetting (meth)acryloyl groups, and also have epoxy groups that can be cationically cured

Embodiment

[0129]Hereinafter, the present invention will be described in more detail through examples. However, the present invention is not limited to each of the following examples, and for example, components of these examples can be appropriately combined with each other. In addition, "%" means "mass %" unless otherwise specified.

Synthetic example 1

[0130] Synthesis example 1 (synthesis of catalyst tristannoxane compound)

[0131] 16.48 g (75 mmol) of dimethyl tin dichloride, 120 ml of water, and 45 ml of ethanol were added to a reaction vessel equipped with a stirrer, a thermometer, and a dropping funnel, and stirred to dissolve evenly. Then, 10.1 g (100 mmol) of triethylamine was dripped from the dropping funnel while stirring. At this time, the reaction vessel was placed in an ice bath to keep the temperature of the contents at about 20°C. After completion of the dropwise addition, the mixture was further reacted with stirring at the same temperature for 3 hours. After the reaction, the white precipitate was filtered, washed with 100 ml of water and then 200 ml of ethanol, and then dried under reduced pressure at 105° C. to obtain 12.6 g of white powder. As a result of elemental analysis (using vario EL manufactured by elementar company), tin is 64.9%, chlorine is 13.0%, and the theoretical value of hexamethyl-1,5-di...

Embodiment 1

[0134] The transesterification reaction (synthesis of acrylate) of embodiment 1 bisphenol A type epoxy resin

[0135] Add bisphenol A type epoxy resin EPICLON AM-040-P (manufactured by Dainippon Ink Chemical Industry Co., Ltd., number average molecular weight Mn=2000, according to GPC) Polystyrene equivalent value) 10.0 g, ethyl acrylate 120.0 g, tristannoxane compound 0.6 g obtained in the above synthesis example as a catalyst, 1.2 g of p-methoxyphenol as a polymerization inhibitor, while introducing air start reacting. The reaction was carried out for 24 hours while ethanol generated at a reaction temperature of 95 to 98° C. was refluxed and removed as a mixed solution with ethyl acrylate.

[0136] After the reaction, excess ethyl acrylate was removed by vacuum distillation, and a small amount of toluene was added to the residue, and then excess ethyl acrylate was removed by vacuum distillation again.

[0137] The reaction mixture remaining after distillation under reduced...

Abstract

Linear (meth)acryloyl-containing compounds characterized by having a structure of structural units of the general formula: (1) [wherein A is a divalent hydrocarbon group optionally containing a heteroatom] linked to each other by groups of the general formula: (2) (3) [in the formula (3), R is a hydrogen atom or methyl] [provided that with respect to A's of the general formula (1), those identical to each other or those different from each other may be linked] and having a molecular terminal of epoxy or compound of the general formula: (4) [wherein R is a hydrogen atom or methyl; and B is a monovalenthydrocarbon group], wherein the sum of contained structural units of the general formula (3) and general formula (4) is 3 or more per molecule on the average, and characterized by having a number average molecular weight of 500 to 10,000.

Description

technical field [0001] The present invention relates to a (meth)acryloyl group-containing compound having an average of 3 or more (meth)acryloyl groups in one molecule, which has excellent curability and can be widely used as a material for curable resin compositions, and a method for producing the same . Background technique [0002] A compound having a (meth)acryloyl group is widely used as a material of a resin composition cured by active energy rays or radicals, or a material of a thermosetting resin composition, or a raw material of a polymer compound. Especially epoxy (meth)acrylate, because the heat resistance, chemical resistance, water resistance, adhesion, mechanical properties, etc. of the obtained cured product are better than those obtained by using other (meth)acrylates, Therefore, it is widely used in coating resins, printing inks, UV curable resins, molding resins, films, adhesives, structural materials, and solder resists for wiring boards. [0003] Conven...
