| abstract |
A polyester resin composition for vibration-damping material containing a thermoplastic polyester resin (A) constituted of a dicarboxylic acid component and a diol component, a plasticizer (B) represented by the general formula (I):n nwherein each of A 1 and A 2 is independently an alkyl group having 4 or more carbon atoms and 18 or less carbon atoms, an aralkyl group having 7 or more carbon atoms and 18 or less carbon atoms, or a mono- or diether of a (poly)oxyalkylene adduct thereof; n is 0 or 1; X is any one of -SO 2 -, -O-, -CR 1 R 2 -, and -S-, wherein each of R 1 and R 2 is independently H or an alkyl group having 4 or less carbon atoms, and wherein each of R 3 and R 4 is independently any one of -O-, -CO-, and -CH 2 -, with proviso that a case where both R 3 and R 4 are -O- is excluded, and an inorganic filler (C). The above composition can be suitably used as a vibration-damping material in manufactured articles, such as materials for audio equipment such as speakers, and electric appliances, or parts or housing thereof. |
