Abstract:
1. A material for vibration control comprising: a composition (X) comprising: 99 to 40 parts by weight of a propylene polymer (A) which is a propylene/ethylene/α-olefin having 4 to 20 carbon atoms copolymer having 1 to 25 mol % of a constitutional unit derived from ethylene and 1 to 35 mol % of a constitutional unit derived from α-olefin having 4 to 20 carbon atoms, while the total constitutional unit contained in the propylene polymer (A) is 100 mol %, and has a melting point measured by DSC of 90° C. or below or has no observed melting point, and wherein the propylene polymer (A), for which an absorption intensity A observed at 22.0 to 20.9 ppm, an absorption intensity B observed at 19.0 to 20.6 ppm, and an absorption intensity C observed at 19.0 to 22.0 ppm assigned to propylene methyl, in the signal chart where a peak at the highest magnetic field among the signals originating from CH (methine) constitutional units derived from α-olefin having 4 to 20 carbon atoms measured by 1 to 60 parts by weight of a propylene polymer (B) which has a melting point measured by DSC of 100° C. or above, while the total of (A) and (B) is 100 parts by weight, and 5 to 50 parts by weight of a hydrogenated terpene resin, to 100 parts by weight in total of the propylene polymer (A) and the propylene polymer (B.
