Abstract
There are herein disclosed a method for preparing a modified resin which comprises thermal/reaction by the use of a norbornenyl group-containing compound typified by norbornenecarboguanamine or its derivative, a method for preparing an epoxy-modified resin which comprises the step of reacting the above-mentioned modified resin and an epoxide, a flame-retarding method, a thermal stabilization method, a compatibilizing method and a surface modification method which comprise utilizing the modified resin, as well as a coating resin composition and an adhesive resin composition containing the modified resin. According to the, preparation methods of the present invention, the deterioration of a material scarcely occurs, and a functional group which is excellent in flame retardancy, thermal stability, compatibility and the like can be introduced to the resins. By the utilization of these techniques, there can be obtained a flame-retardant material having a good char formability, a thermally stable material whose molded articles can inhibit heat deterioration, a material excellent in miscibility between different kinds of resins, a surface-modified material which is excellent in adhesion a…
