A composition of matter is disclosed that comprises a compound of the formula A
n
R, wherein:
A is
1
R
1
is hydrocarbyl;
m is 0 or 1;
n is 1, 2, or 3;
R is selected from the group consisting of:
mono-, di-, and trivalent aliphatic groups; mono-, di-, and trivalent aromatic groups; five- and six-membered heterocyclic rings comprising n carbon atoms bonded to A, at least one nitrogen atom, and, optionally, at least one sulfur atom; and
2
wherein R
2
and R
3
are independently selected from the group consisting of hydrogen and hydrocarbyl. These compounds are useful as coupling agents in filled elastomer compositions.
本发明公开了一种物质组合物,其包括公式AnR的化合物,其中:A是1R1是烃基;m为0或1;n为1、2或3;R从以下组中选择:单价、二价和三价脂肪族基;单价、二价和三价芳香族基;含有n个碳原子与A结合的五元和六元杂环环,至少一个氮原子,以及可选地至少一个
硫原子;其中R2和R3独立地选择自氢和烃基组成的组。这些化合物在填充弹性体组合物中作为
偶联剂是有用的。
