FIELD: chemistry.
SUBSTANCE: described is a composition for obtaining a binding agent for soaking cellulose fibres. The composition contains polyolefin resin which reacts with 1.6-4.0% maleic anhydride. The composition has less than 1500 ppm free maleic anhydride. The resin has melt flow index at 190°C and 2.16 kg ranging from approximately 0.1 to 500 g/10 min. The composition has yellowing index of 20-70. The polyolefin is polyethylene. Described also is a cellulose composite containing 10-90% cellulose fibre; a first polyolefin resin having melt flow index from 0.1 to 100 g/10 min; 0.1-10 wt % composition for obtaining the binding agent. The maleic anhydride is grafted on the polyethylene.
EFFECT: high binding efficiency of the binder.
