THERMOPLASTIC ELASTOMER COMPOSITION, POWDER, PELLETS, AND MOLDINGS |
摘要 |
<p>A thermoplastic elastomer composition comprising the following components (A), (B-1) and (B-2), wherein the total content of the components (B-1) and (B-2) is 10 to 250 parts by weight per 100 parts by weight of the component (A) and the complex dynamic viscosity eta <*>(1) at 250 DEG C is 1.5 x 10<5> P or below while the Newtonian viscosity index (n) is 0.67 or below; and pellets and moldings made from the composition: (A) a polyolefin resin, (B-1) an optionally hydrogenated conjugated diene rubbery polymer which exhibits two tan delta peaks in the temperature range of -70 to 30 DEG C in the tan delta temperature dependence curve as determined by the solid viscoelasticity measurement of the composition prepared by kneading this rubbery polymer and the resin (A), and (B-2) an optionally hydrogenated conjugated diene rubbery polymer which exhibits a single tan delta peak at a temperature which falls within the range of -70 to 30 DEG C and is different from the tan delta peak temperatures of the components (A) and (B-1) in the tan delta temperature dependence curve as determined by the solid viscoelasticity measurement of the composition prepared by kneading this rubbery polymer and the resin (A).</p> |
