Tire has thread comprising rubber composition containing low molecular weight polyester such as polyester sebacate and triethylene glycol caprate-caprylate

摘要

Tire has thread comprising rubber composition containing diene-based elastomer(s) (in phr) (100) and low molecular weight polyester (1-20) based upon conjugated diene based elastomer (100). The polyester is polyester sebacate, triethylene glycol caprate-caprylate, triethylene glycol diheptanoate, triethylene glycol dipelargonate and/or triethylene glycol di-2-ethyl hexoate. Tire has thread comprising rubber composition containing diene-based elastomer(s) (in phr) (100) and low molecular weight polyester (1-20) based upon conjugated diene based elastomer (100). The polyester is polyester sebacate having molecular weight of 1000-3000 so long as it has a melting point of less than 0[deg]C, triethylene glycol caprate-caprylate having molecular weight of 430, triethylene glycol diheptanoate having molecular weight of 388, triethylene glycol dipelargonate having molecular weight of 420 and/or triethylene glycol di-2-ethyl hexoate having molecular weight of 374.
