Abstract

PROBLEM TO BE SOLVED: To provide a curable epoxy resin composition containing a new O- silylated phenol derivative as a component compound and giving a cured product having low surface free energy, low water-absorptivity, excellent electrical properties, high glass transition temperature and excellent heat-resistance. SOLUTION: The objective curable epoxy resin composition is produced by reacting a tetrakisphenol compound with a substituted silylation agent to obtain an O-silylated phenol derivative of general formula (1) such as 1,1,2,2- tetrakis(4-trialkylsiloxyphenyl)ethane useful as a curing agent and compounding the obtained compound of formula (1) with an epoxy resin and a catalyst for curing reaction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a novel O-silylated phenol derivative, a method for producing the same, a cured epoxy resin composition and a cured epoxy resin, and more particularly to a novel O-silylated phenol having a tetrakisphenyl skeleton. A phenol derivative, a method for producing the O-silylated phenol derivative, an epoxy resin cured composition containing the novel O-silylated phenol derivative as a curing agent, and an epoxy obtained by curing the epoxy resin cured composition. It relates to a cured resin.

[0002]

2. Description of the Related Art Epoxy resins are widely used in various fields because of their excellent mechanical and thermal properties. However, a general-purpose bisphenol A diglycidyl type epoxy resin has a hydroxyl group represented by the following formula (3) in the structure and, when cured with a usual phenol or amine-based curing agent, more epoxy resin is contained in the cured product. A hydroxyl group is generated, and a cured product containing a large number of hydroxyl groups has high surface free energy and high water absorption, and has a problem in water resistance and electrical insulation when used as an electric / electronic material. Therefore, the development of a new curing agent that can suppress the generation of new hydroxyl groups due to the curing reaction has been strongly desired.

Attention has been focused on polymer synthesis using a silylated compound such as a silylated diamine as a curing agent. For example, the reaction of an allylsilyl ether in which active hydrogen has been substituted with a silyl group with an epoxy compound is described in Tetrahedron Letters.
tters) 31,1723 (1990), and the reaction of an O-silylated amine in which active hydrogen is substituted with a silyl group with an O-silylated polyepoxy compound is described in JP-A-8-245749. The epoxy resin cured product obtained by these reactions is a hydrophobic cured product having fewer hydroxyl groups and siloxy groups than the cured product obtained from a general phenol and amine curing agent, and has water resistance and electrical insulation properties. Shows excellent properties. However, since the cured product obtained by this method has a weak intermolecular association force between polymers due to the presence of a hydrophobic siloxy group having no associative property, an epoxy resin containing a large amount of a conventional hydroxyl group that forms an intermolecular hydrogen bond is used. It is not sufficiently satisfactory from the viewpoint of a heat-resistant material having high industrial value, for example, the glass transition temperature is significantly lower than that of a cured product.

[0005]

The O represented by the general formula (1) of the present invention
-Among the silylated phenol derivatives, from the viewpoint of the reactivity and compatibility with the epoxy resin, particularly 1,1,2,2-tetrakis (4-trialkylsiloxyphenyl) ethane, 1,1,2,2-tetrakis (3-methyl-4-trialkylsiloxyphenyl) ethane, 1,1,2,2
-Tetrakis (3,5-dimethyl-4-trialkylsiloxyphenyl) ethane is preferred.

In the tetrakisphenol compound represented by the general formula (2), R ² and R ³ each represent a hydrogen atom, a lower alkyl group, an optionally substituted phenyl group, a halogen atom or a lower alkoxy group. A lower alkyl group is a C1-C8 alkyl group, a halogen atom is chlorine, bromine, fluorine or iodine, and a lower alkoxy group is a C1-C8 alkyl group.
Examples of the substituent of the optionally substituted phenyl group in the alkoxy group include an alkyl group, an alkoxy group, and a halogen group.
