Abstract
A novel resin composition is obtained by blending a hydrophilic pullulan with 2 to 98 wt %, based on the total resin weight, of a hydrophobic thermoplastic resin. In case the amount of the thermoplastic resin is 2 to 50 wt %, there is obtained a resin composition consisting essentially of the pullulan which is excellent in water resistance, while in case the amount of the thermoplastic resin is 50 to 98 wt %, there is obtained a resin composition consisting essentially of the thermoplastic resin which has been improved in water and moisture absorptivity.
