 note = {Large quantity of saw dust appears every day in saw-mills and utilizing the dust we tried to obtain plastics.
Saw dust ground into fine powder is treated with dil. H_2SO_4 under normal pressure in order to activate the lignin in It.
Anilin, formalin or rosin, etc. is added, and then, it is moulded under pressure at high temperature. After this procedure, we examined tbe chemical, mechanical and electrical characters of tbe plastics thus obtained. Some Bakelite powder is added to this, obtaining quite satisfactory result., Article, 富山大学工学部紀要，3(1)，1951-12, Page 39-44},
