摘要：
A material for vibration control of the invention includes a propylene polymer (A) containing a constitutional unit (a) derived from propylene in the proportion of 40 to 100 mol % and a constitutional unit (b) derived from α-olefin having 2 to 20 carbon atoms excluding propylene in the proportion of 60 to 0 mol % [provided that the total of (a) and (b) is 100 mol %], and having a melting point measured by DSC of 90° C. or below or no observed melting point, and the material has excellent vibration controllability such as vibration damping property, vibration preventing property, sound insulating property, and sound absorbing property.
