[Prior Art 1 Epoxy resins are widely used in various industrial fields due to their excellent mechanical properties. In particular, epoxy resins are often used in composite materials made of reinforcing fibers such as carbon fibers, glass fibers, and aramid fibers and matrix resins. In recent years, as the applications of these composite materials have expanded, new properties have come to be required of the epoxy resins used, but there are still unsatisfactory aspects and limitations in their applications and usage methods. . One of these is improvement in moldability. This problem is caused by the following phenomenon.

Epoxy resin becomes considerably low in viscosity at high temperatures, and F
When molding RP, it has great advantages such as making it easier to impregnate the reinforcing fibers and making it easier for air bubbles to appear inside the molded product, but on the other hand, if the viscosity is too low, the resin may become unnecessary if the molded product is large and thick. There is a certain appropriate range for the viscosity during molding because excessive flow may cause problems with disorder of reinforcing fibers and dimensional viscosity. However, when trying to increase the viscosity at high temperatures, the viscosity at room temperature also increases, resulting in a resin composition with poor tack and drape properties, making it unsuitable for practical use.

In order to solve such problems, it is generally known to add a polymer to adjust the viscosity at high temperatures. Various types of polymers are known to be added, but when heat resistance is important, it is preferable that the polymer added has as high a glass transition temperature (Tq) as possible, and is also preferably one that dissolves uniformly in the epoxy resin. If you roughly consider the mechanical properties of the cured product, the polymer added also has a certain level of stability.
A well-balanced one is desirable.
