MIXED COMPLEX CELLULOSE NITRATE ESTERS CONTAINING MALEINATE GROUPS AS HIGH-MOLECULAR WEIGHT SUBSTRATE FOR ADHESIVE, PAINT AND POLYMERIC MATERIALS, PROCESS FOR PREPARATION THEREOF

摘要

FIELD: claimed invention describes new chemical compounds, more particularly mixed complex cellulose nitrate-maleinate esters which are high molecular substrate of adhesive, print and polymeric materials. SUBSTANCE: mixed complex cellulose nitrate-maleic cellulose esters are prepared from high nitrogen cellulose nitrates or pyroxyline powders on expiry of service life thereof. Said compounds have reduced combustibility, better film-forming properties. They are useful as polymers substrate for adhesives, varnishes, paints and also as fuel compounds having reduced combustion rate. Cellulose nitrate or pyroxyline powders are condensed in solvent in admixture with maleic anhydride during heating and stirring operations. To obtain free-flowing product of small electrolizing power, precipitation is carried out by adding certain amounts of components at 30-60 C and water having the same temperature. EFFECT: improved properties of the substrate.
