<P>PROBLEM TO BE SOLVED: To provide a polyester elastomer resin composition showing viscosity characteristics corresponding to various kinds of molding methods and processes, which can not be solved by the prior arts. <P>SOLUTION: The polyester elastomer resin composition comprises a thermoplastic polyester elastomer [A] showing solution viscosity of 2.3 to 2.8 and a plasticizer [B], in proportions satisfying formula 1 which is 0.01≤W(B)/W(A)≤0.1, and shows elongational viscosity of 100,000 Pa s to 1,000,000 Pa s after one second of the test at 180°C and 6 rpm rotation. In formula 1, W(B)/W(A) represents a mass proportion of the plasticizer [B] to the thermoplastic polyester elastomer [A] in the polyester elastomer resin composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
