    摘要: The present invention relates to novel aminosilane-functionalized diene compounds of the following Formula I: wherein each R′ is independently selected from C1-C12 alkyl, C6-C18 aryl, C7-C18 alkylaryl, tri(C1-C6 alkyl, C6-C12 aryl or C7-C18 alkylaryl)silyl and allyl, wherein two R′ groups may be connected to form a ring and the ring may contain, further to the Si-bonded nitrogen atom, one or more of an oxygen atom, a nitrogen atom, an >N(C1-C6 alkyl or C7-C18 alkylaryl) group and a sulfur atom; each R″ is independently selected from C1-C6 hydrocarbyl; Ra, Rb, Rc, Rd and Re are independently selected from hydrogen, methyl and ethyl; x is an integer selected from 0, 1 and 2, y is an integer selected from 1, 2 and 3 and x+y=3. The diene compounds are useful as modifying monomers in the polymerization of conjugated diene monomers.
