Описание:
The article is devoted to investigation of reinforcement effeiciency of the agents received on the basis of styrene copolymers and maleic anhydride on the properties of paper made of recycled pulp. It was established that for modification of styrene copolymers it is resonable to use NH4OH. Preferred content of maleic anhydride is 20−22 mol. %. The molecular weight of maleic anhydride copolymers should be in the range of 5,500−6,500 c. u. The reinforcement of styrene copolymers is manifested when the content of them in fibrous slurry is 0.5% of the mass of a. d. s. Drying temperature (120±2ºC) increases this effect, the strength of paper samples testifies it.
