<P>PROBLEM TO BE SOLVED: To provide a molding material having a good thermoplasticity, and excellent in terms of molding properties (melt volume flow rate), heat resistance (deflection temperature under load), rigidity (bending modulus) and impact resistance (falling ball impact strength). <P>SOLUTION: The molding material includes a cellulose derivative, containing groups obtained by substituting the hydrogen atoms of hydroxy group contained in the cellulose with the following (A) and the following (B), and a polyether compound containing repeating units expressed by either general formulas (p1) or (p2) and having terminal groups expressed by the following general formula (p1-1), (p1-2), (p2-1) or (p2-2): (A) a hydrocarbon group: -R<SB POS="POST">A</SB>, (B) an acyl group: -CO-R<SB POS="POST">B</SB>(wherein, R<SB POS="POST">B</SB>is a hydrocarbon group), -CH<SB POS="POST">2</SB>CH(R<SB POS="POST">p</SB>)O-: (p1), -(CH<SB POS="POST">2</SB>)<SB POS="POST">p</SB>O- (p2), -CH<SB POS="POST">2</SB>CH(R<SB POS="POST">p</SB>)O-R<SB POS="POST">m1</SB>(p1-1), R<SB POS="POST">m2</SB>-CH<SB POS="POST">2</SB>CH(R<SB POS="POST">p</SB>)O- (p1-2), -(CH<SB POS="POST">2</SB>)<SB POS="POST">p</SB>O-R<SB POS="POST">m1</SB>(p2-1), and R<SB POS="POST">m2</SB>-(CH<SB POS="POST">2</SB>)<SB POS="POST">p</SB>O- (p2-2). <P>COPYRIGHT: (C)2012,JPO&INPIT |
