The invention relates to the use of triazenes of formula (I) wherein Q is a direct bond or a bivalent radical -(CR8R9)-, Z1 is -O-, -NR10-, -CH2-,-(CR11R12)- or -C(=O)- and R1 to R12 are optionally substituted hydrocarbon residues, as precursors for radicals useful in reactions triggered by free radicals, such as polymerization of unsaturated monomers and degradation of polyolefins. Most of the triazenes of formula (I) are novel and claimed, too, as well as the preparation of triazenes of formula (I) and polymerisable compositions comprising them.
该发明涉及使用式(I)中的三氮烯,其中Q是直接键或二价基团-(CR8R9)-,Z1是-O-,-NR10-,-CH2-,-(CR11R12)-或-C(=O)-,R1至R12是可选择取代的碳氢基团,作为自由基引发的反应中有用的自由基前体,例如不饱和单体的聚合和聚烯烃的降解。大多数式(I)中的三氮烯是新颖的并且被声明为专利,还包括制备式(I)中的三氮烯以及包含它们的可聚合组合物。
