摘要： The object of the invention is to provide sound insulating members exhibiting both high vibration damping performance and high sound insulation performance, a vibration damping material for affording such members and a resin composition for forming the vibration damping material. The invention provides a first resin composition for vibration damping materials which contains 100 parts by weight of a chlorine-containing thermoplastic resin, and 20 to 200 parts by weight of a chlorinated paraffin having 12 to 16 carbon atoms on average. The thermoplastic resin contains preferably 20 to 70 wt. %, more preferably 30 to 70 wt. %, of chlorine. The chlorinated paraffin is preferably 30 to 70 wt. %, more preferably 35 to 65 wt. %, in chlorination degree.

摘要： An object of the invention is to provide a damping material resin composition which is great in loss tangent, exhibits outstanding damping properties and enables a damping material to retain its own shape. The invention provides a damping material resin composition comprising 100 parts by weight of a thermoplastic resin having a chlorine content of 20 to 70 wt. % and a weight average molecular weight of at least 400,000, and 100 to 1000 parts by weight of a chlorinated paraffin having a chlorine content of 30 to 75 wt. % and 12 to 50 carbon atoms. (Preferably, the chlorinated paraffin contains 10 to 70 wt. % of a chlorinated paraffin having a chlorine content of at least 70 wt. %.)
