The glue is preferably prepared from native starch according to the Stein-Hall method by first gelatinizing a part of the native starch in water in an alkaline medium. This is followed by addition of the rest of the water, the starch and other additives, such as boron chemicals or resins, under non-gelatinizing conditions. The gelatinized starch is then decomposed by addition of a water soluble oxidant in situ at 10 - 100.degree. C. to obtain the final product. 9/1/81 -6-WRR/SV/2A-8</p> |
