摘要： Adhesives or pastes prepared by dissolving or dispersing uniformly a pullulan ester and/or pullulan ether in water or in a mixture of water and acetone in an amount between 5 percent and 40 percent of the solvent are moisture-proof and have better water retention, stability and adhesiveness than conventional starch pastes or glue. They are also non-toxic and resistant to the growth of fungi.

摘要： Pullulan esters are prepared by the reaction of pullulan with aliphatic or aromatic fatty acids or their derivatives in the presence of suitable solvents and/or catalysers. Said pullulan esters can be shaped by compression molding or extrusion at elevated temperature or by evaporation of solvents from their solutions to form shaped bodies, such as films or coatings which are practically impermeable to atmospheric oxygen in thin layers and unaffected by oils and fats so as to provide valuable packaging materials for food, pharmaceuticals, and other oxygen sensitive materials.

摘要： Pullulan reacts with alkylating agents such as dimethyl sulfate, diethyl sulfate, ethylene oxide, and propylene oxide to form the corresponding lower-alkyl or hydroxy-lower-alkyl ethers which are much less soluble in water than pullulan, but retain sufficient sensitivity to moisture to be biodegradable when they do not contain more than one, and preferably not more than 0.5, alkoxy or hydroxyalkoxy group per glucose unit in the pullulan molecule. Films and fibers of the ethers are mechanically strong and are readily plasticised with water-soluble polyhydric alcohols. The ethers can be molded above their softening temperature in conventional injection or compression molding equipment. The films are practically impervious to atmospheric oxygen and suitable as packaging material.
