いて強く望まれていた。(Prior art) Polyamide is the most typical engineering plastic, and has excellent mechanical strength, abrasion resistance, heat resistance, chemical resistance, and good moldability, so it is used in many materials such as gears, rolls, and sliding plates. It is also used as a mechanical part. However, since polyamide has low impact resistance in an absolutely dry state (low moisture absorption state), its uses are limited, and improvements in this point have been strongly desired in the art.

No. 4,355,139) However, in all of these (11 (21) (31) proposals, when the elastomer component is kneaded and dispersed in molten polyamide, it is essential that the elastomer component is also in a molten state, and when using rubber as the elastomer component, it is essential that the elastomer component is in a molten state. A sulfuric state was an essential condition.
即ち、加硫ゴムをポリアミド中に微粒子状に混練分散す
ることは加硫ゴムが流動性を示さないために非常に困難
であろうと考えられていたのである。That is, it was thought that it would be extremely difficult to knead and disperse vulcanized rubber into polyamide in the form of fine particles because vulcanized rubber does not exhibit fluidity.

用方法がな〈産業廃棄物として埋立に使用されていた。On the other hand, in the industrial rubber product industry, how to handle and effectively utilize vulcanized rubber scraps, which are increasing year by year, has become an issue. For example, in the process of manufacturing a timing belt, a high degree of dimensional accuracy is required for the belt thickness, so the back surface rubber layer of the belt is ground with a grinder after vulcanization molding. Various methods are being considered to reuse the rubber powder generated during this process, but there is currently no suitable way to utilize it (it was used in landfills as industrial waste).
