A compound includes at least one group Q and at least one group A linked together by at least one “spacer” group Sp, in which:
group Q includes a dipole containing at least one nitrogen atom, preferably a nitrile oxide, nitrone, or nitrile imine function;
group A contains at least one nitrogen atom, and is preferably an imidazolidinyl, ureyl, bis-ureyl, ureido-pyrimidyl, and triazolyl group; and
Sp is an atom or a group of atoms forming a link between Q and A, preferably, a linear, branched or cyclic hydrocarbon-based optionally substituted chain, and may contain one or more aromatic radicals and/or heteroatoms. The compound may react with an unsaturated polymer forming a covalent bond with the polymer. The compound is useful for providing good interaction between fillers and polymers by establishing labile, non-covalent bonds between the polymer chains and the filler, thereby limiting processing problems.
化合物包括至少一个含有至少一个氮原子的偶极子的Q基团,优选为腈氧化物、亚硝基或腈亚胺基团,以及至少一个含有至少一个氮原子的A基团,优选为咪唑烷基、尿素基、双尿素基、尿素基嘧啶基和三唑基团;以及至少一个“间隔”基团Sp将Q和A连接在一起,优选为线性、支链或环烃基可选取代链,可包含一个或多个芳香基团和/或杂原子。该化合物可以与不饱和聚合物反应,与聚合物形成共价键。该化合物有助于通过在聚合物链和填充物之间建立不稳定的非共价键,从而限制加工问题,提供填充物和聚合物之间良好的相互作用。
