PULLULAN AMINOALKYL ETHER ABSTRACT Of THE DISCLOSURE Pullulan aminoalkyl ether is obtained by reacting pullulan with an aminoalkylating agent in a solvent in the presence of an alkali. This ether may be used as a cationic polymer of considerable utility in industries. For instance, when used in a paper coating material, it gives desirable effects on gloss, RI dry pick, and RI wet pick and, furthermore, as compared with pullulan, markedly improves physical properties of the coated paper such as tearing strength, tensile strength and wrinkle recovery; it improves also retention of load- ing materials such as clay and calcium carbonate.
