METHOD OF PREPARING STRUCTURIZED PHENOLIC RESIN FROM PHENOL AND ACETONE WASTE BY CUMENE METHOD Russian patent published in 1997 - IPC

Abstract RU 2081103 C1

FIELD: chemical technology. SUBSTANCE: method is based on modification of phenolic resin properties at physico-chemical treatment. Resin is heated to 80-90 C followed by natural cooling to 0 C, keeping at this temperature for 10-15 h and heating to the room temperature. Except for, low-molecular polyethylene is added, additionally, to heavy phenolic resin at amount 15-25%. Processed phenolic resin is used as entomological glue composition for forest protection against pests at temperature from minus 5 C to +50 C. EFFECT: highrer efficiency. 3 cl, 1 tbl
