DETERIORATION TEST METHOD FOR VULCANIZED RUBBER COMPOSITION CONTAINING AGE RESISTOR, RUBBER COMPOSITION AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a deterioration test method whereby a decrease of an age resistor in an age resistor-containing rubber can be reproduced in a short period.;SOLUTION: This invention relates to a deterioration test method for a vulcanized rubber composition containing an age resistor, characterized in that a vulcanized rubber composition is immersed in an organic solvent with a solubility parameter of 10 to 13 and an age resistor in the vulcanized rubber composition is decreased.;COPYRIGHT: (C)2015,JPO&INPIT
