METHOD FOR PRODUCTION OF EPOXY NITRATES OF CELLULOSE FOR POLYMER BASE OF SOLID POLYMER COATINGS, ADHESIVES AND SOLID FUEL Russian patent published in 1998 - IPC

Abstract RU 2106368 C1

FIELD: production of polymers for solid polymer coatings, adhesives and solid fuel having decreased combustion rate. SUBSTANCE: nitrocellulose (nitrogen content in it being 12.5-13.5 %) or pyroxylin gunpowder is mixed with epoxy resin, peptizing agent and with stabilizing agent, the process is carried out in solution. Thus prepared product is affected by thermal mechanical treatment on heated rolls, the process takes place within 15-20 min at 70-80 C. Then fabric is rolled out and cooled, ratio of nitrocellulose and epoxy resin being (80:20)-(20:80). EFFECT: increased rate of reaction without using catalyst; simplified method for production of epoxy nitrates of cellulose; increased degree of epoxidation; increased degree of utilization of nitrocellulose gunpowder after their prolonged storage. 1 tbl
