Rubber compositions containing borate compounds

摘要

The present invention relates to rubber compositions containing borate compounds of the formulawherein R1 and R2 are independently selected from the group consisting of alkoxy radicals having from 1 to 8 carbon atoms; R3 is selected from the group consisting of alkylene groups having from 1 to 15 carbon atoms and arylene and alkyl substituted arylene groups having from 6 to 10 carbon atoms; X is selected from the group consisting ofand Y is selected from the group consisting ofwhere x is an integer of from 1 to 8.
