FIELD: chemical engineering.
SUBSTANCE: method involves bringing chitosan and aqueous solution of acrylic acid in interaction under heating in 1:1-2:1 mole proportion, treating with potassium hydroxide, precipitating with acetone and drying the product. Acrylic acid is used as 10-20% aqueous solution. Source reagents are preliminarily kept at room temperature until gel is formed. Heating to 50-70°C is applied for 12-24 h.
EFFECT: high joining degree of acrylic acid to chitosan.
