A method for producing a characteristic thermosetting resin is provided.
以下本発明について詳述する。The present invention will be explained in detail below.

When small heavy oils or pinch oils are used, a resin having a poor degree of crosslinking is produced because there are few hydrogen atoms in the aromatic ring. In particular, it is preferable to use a material having an fa value of 0.7 or more and a) Ha value of 30% or more.

る以前に常圧又は加圧下で降温させて反応を停止する。When the reaction proceeds in this way, one reaction mixture undergoes a polycondensation reaction and its molecular weight increases, but since the reaction system is maintained under reduced pressure, low molecular weight substances that are by-produced in the polycondensation reaction do not react. It is removed from the system and the reaction is significantly accelerated. If the heating reaction is further advanced, an insoluble and infusible cured product is produced, but in the present invention, the reaction is stopped by lowering the temperature at normal pressure or under increased pressure before an insoluble and infusible cured product is produced.

緻密な固体状物となる。The foaming state caused by volatilization of low molecular weight substances produced as by-products during the reaction under reduced pressure disappears when the reaction system is maintained at normal pressure or increased pressure. Therefore, when the temperature is lowered, the reaction product is cooled in a non-foamed state and the reaction is stopped, and as a result, the obtained thermosetting resin does not become a porous body.
It becomes a dense solid.
