Thermoplastic elastomer composition and method for producing the same |
| abstract |
The present invention provides a thermoplastic elastomer composition capable of forming a molded body excellent in low-temperature impact resistance. Preparation of thermoplastic thermoplastic containing crystalline olefin-based polymer (A) and ethylene-α-olefin (4 to 20 carbon atoms)-non-conjugated polyene copolymer (B) satisfying the following conditions (1) and (2) Elastomer composition. (1) Formula: The B value represented by ([EX]+2[Y])/[2×[E]×([X]+[Y])] is 1.20 or more. Here, [E], [X] and [Y] represent the molar fraction of structural units derived from ethylene, the molar fraction of structural units derived from α-olefins having 4 to 20 carbon atoms, and the molar fractions of structural units derived from non-conjugated polyenes, respectively. The molar fraction of the structural unit, [EX] represents the structural unit derived from ethylene - the structural unit derived from α-olefin having 4 to 20 carbon atoms. (2) The molar ratio of the structural unit derived from ethylene to the structural unit derived from the α-olefin (4 to 20 carbon atoms) in the copolymer (B) is 40/60 to 90/10. |
