<p>Disclosed is a molding material having good dispersibility and also having good bending elastic modulus, bending strength, Charpy impact strength and moldability with in a well-balanced manner. The molding material comprises at least two cellulose derivatives each of which contains at least one group that is produced by substituting a hydrogen atom in a hydroxy group contained in a cellulose by (A) a C1-3 hydrocarbon group -RA composed only of carbon and hydrogen and at least one group that is produced by substituting a hydrogen atom in a hydroxy group contained in the cellulose by (B) an acyl group -CO-RB (wherein RB represents a C4-11 hydrocarbon group composed only of carbon and hydrogen), wherein the solubility parameters (SP values, unit: (cal/cm3)1/2) of the cellulose derivatives are different from each other, the difference between the SP values is greater than 0.3, and the SP value of one of the cellulose derivatives which has the highest SP value is less than 10.5 (cal/cm3)1/2.</p> |
