<p><P>PROBLEM TO BE SOLVED: To provide a polymer-filler coupling compound represented by the formula:B-A-S<SB>x</SB>-N, to provide a vulcanizable rubber composition containing the coupling compound, and to provide a method for producing the rubber composition. <P>SOLUTION: The coupling compound is such that B is an azaheterocyclic oxygen or sulfur-containing moiety or an allyltin moiety; S<SB>x</SB>is a polysulfide, wherein x is between 2 and about 10; A is a linking atom or group that forms a bridge between B and S<SB>x</SB>; and N is a blocking group. S<SB>x</SB>can be a disulfide. N can be a conventional blocking group or other group such as -A-B. This coupling compound is to be used for modifying polymers containing unsaturated carbon-carbon bonds and for promoting filler dispersion. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
