Abstract
The present invention is directed to novel silane disulfide vegetable oils, a method of making the oils, their use in rubber compositions, and their use in tires.
Claims17
A vegetable oil derivative comprising the structure
- where R1, R2, and R3 are independently C15-C20 alkenyl, C15-C20 alkyl, and optionally containing aromatic groups;
- R4 is —S—S—R7— or R4 is —S—X—S—S—R7— where X is unsubstituted C1 to C10 alkane diyl;
- R5, R6 are independently C1 to C10 alkyl, R7 is C1 to C10 alkane diyl, j=0 to 2, k=1 to 3, and j+k=3;
- wherein each R4 is attached via a carbon-sulfur linkage to one of R1, R2 or R3;
- and m is the number of the carbon-sulfur linkages based on olefinic unsaturation of R1, R2 and R3.
2 more elements
A method of making a vegetable oil derivative comprising the steps of:
- obtaining a thiolized triglyceride;
- and
- reacting the thiolized triglyceride with a silane disulfide comprising a silyl group at one terminus and a leaving group at the other terminus, to produce the vegetable oil derivative.
