Epoxy resin is a typical example of thermosetting resin. This epoxy resin is widely used as a matrix resin for civil engineering, architecture, electrical equipment molding materials, paints, linings, adhesives, and FRP. In particular, FRP made of reinforcing fibers such as carbon fibers, glass fibers, and aromatic polyamide fibers and an epoxy resin matrix resin is widely used as a structural material for sporting goods, aircraft, and the like. The properties required of such a matrix resin for FRP include heat resistance, impact resistance, and fatigue resistance. However, epoxy resins do not have sufficient impact resistance, and various methods have been proposed to improve their impact resistance (
For example, JP-A-67-121450.58-14126.
62-36421 and 62-57417).

However, most of these methods significantly reduce the elastic modulus and heat resistance inherent in the epoxy resin, and therefore the resulting FRP does not fully satisfy physical properties, particularly toughness.

C=0 H3 [Problem to be solved by the invention] The present invention improves the toughness of thermosetting resin compositions used as matrix resins for civil engineering, architecture, electrical equipment molding materials, paints, linings, adhesives, and FRP. The purpose of the present invention is to provide a toughening agent that can improve the toughness.

[Means for Solving the Problems] According to the present invention, in order to solve the above problems, a toughening agent for thermosetting resin compositions comprising a carboxylic acid-modified phenoxy resin represented by the following formula is provided.

上式中、nは200〜400の整数を表し、Xおよびy
の組成比率x/yは5〜200であるものとする。
In the above formula, n represents an integer of 200 to 400, and X and y
It is assumed that the composition ratio x/y is 5 to 200.

In the carboxylic acid-modified phenoxy resin represented by the above-mentioned formula, when n is less than 200, the molecular weight is low;
The effect of improving toughness becomes smaller. If n is larger than 400, the compatibility with the epoxy resin will be insufficient and no improvement in toughness can be expected. In terms of the effect of improving toughness, n is 25.
It is preferable that it is 0-350. Moreover, when x/y is smaller than 5, the crosslinking density becomes high due to the reaction between the carboxyl group in the resin and the epoxy resin, and the effect of improving toughness becomes small. On the other hand, if x/y is larger than 200, the reaction between this resin and the epoxy resin will not proceed, and the effect of improving toughness will be insufficient.
