RUBBER COMPOSITION, HETEROCYCLE-MODIFIED GLYCERIN FATTY ACID ESTER, AND PRODUCTION METHOD FOR HETEROCYCLE-MODIFIED GLYCERIN FATTY ACID ESTER

摘要

An object of the present invention is to provide a rubber composition having excellent processability, a heterocycle-modified glycerin fatty acid ester, and a production method for the heterocycle-modified glycerin fatty acid ester. The present invention includes: a rubber composition containing a rubber, silica, and a heterocycle-modified glycerin fatty acid ester, in which an epoxy group is modified with a heterocyclic compound having a heterocycle having at least one H-N bond, where the heterocycle is at least one selected from the group consisting of a piperazine ring, a morpholine ring, and a thiomorpholine ring, and the heterocycle may have a substituent; the heterocycle-modified glycerin fatty acid ester; and a production method therefor.
