<p><P>PROBLEM TO BE SOLVED: To provide a rubber composition capable of achieving higher elasticity and lower heat generation while suppressing substantial lowering of tensile elongation. <P>SOLUTION: The rubber composition is prepared by compounding 100 pts.mass of a diene-based rubber with 10-150 pts.mass of carbon black and 1-50 pts.mass of a thermoplastic polyester resin containing in the molecule 20-50 mass% of a rubber block comprising a polymer of isoprene and/or 1,3-butadiene, and dispersing the thermoplastic polyester resin in the diene-based rubber. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
