Nitrile oxide, nitrone, and nitrile imine compounds
View Patent ↗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.
