Disclosed are polymeric quaternary ammonium salts based on morpholine of general formula:,wherein R and R` =, n=13,9; (1)R and R'=, m=0,414, n=2,9; 2,4; 2,3; 2,2; (2-5)R and R` =, n=6,5; (6)R and R` =, n=10,4; 7,4; 5,2; 4,7; (7-10)R =,R` =, n=2,8, (11)as additives to the composition based on cellulose triacetate for producing film materials. Use thereof allows to decrease viscosity of cellulose triacetate solutions, to increase film strength and relative hardness. |
