Title:
THERMOPLASTIC POLYMER COMPOSITION AND APPLICATION THEREOF
Document Type and Number:
Japanese Patent JP2018172532
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic polymer composition realizing both excellent stress relaxation properties (shape followability) and flexibility.SOLUTION: There is provided a thermoplastic polymer composition which includes (A) a 4-methyl-1-pentene/α-olefin copolymer composed of 63 to 80 mol% of (i) a constitutional unit derived form 4-methyl-1-pentene, 20 to 37 mol% of (ii) a constitutional unit derived from at least one kind of α-olefin selected from 2-20C α-olefin exclusive of 4-methyl-1-pentene and 0 to 10 mol% of (iii) a constitutional unit derived from a non-conjugated polyene (provided that the total of the constitutional units (i), (ii) and (iii) amounts to 100 mol%) and (B) a thermoplastic elastomer composition produced by dynamically crosslinking a mixture including [I] an ethylene/3-20C α-olefin/non-conjugated polyene copolymer and [II] a polyolefin resin and has a mass ratio (A)/(B) of the copolymer (A) to the composition (B) of 90/10 to 50/50. There are also provided a molded body and a grip material each comprising the resin composition.SELECTED DRAWING: None
