    • A cyclic phosphazene crosslinked by piperazine is provided to contain no halogen, show high heat-resistance due to a crosslinked structure by the piperazine, and have high flame-retardant effect by forming a thick char film on the surface of a resin. A flame-retardant resin composition comprising the same is provided to show excellent compatibility with other resinous ingredients, process easiness, mechanical properties and thermostability. A cyclic phosphazene crosslinked by piperazine is obtained by crosslinking a cyclic phosphazene compound represented by a formula(1) with piperazine and is characterized in that 1-90% of the piperazine regarding the total number of OR group(s) of the cyclic phosphazene compound is crosslinked. In the formula(1), R is an aromatic group selected from the group consisting of phenyl, naphthyl and benzyl substituted or unsubstituted by one to three C1-4 alkyl(s); and m is an integer from 3 to 25. A flame-retardant resin composition comprises a resin ingredient consisting of a thermosetting resin, a thermoplastic resin, or a mixture thereof, and a retardant, wherein 1-80 parts by weight of the cyclic phosphazene crosslinked by the piperazine as the retardant is contained regarding 100 parts by weight of the resin ingredient.
    • 提供由哌嗪交联的环状磷腈不含卤素,由于哌嗪具有交联结构而具有高的耐热性,并且通过在树脂的表面上形成厚的焦炭膜而具有高的阻燃效果。 提供包含该阻燃树脂组合物的阻燃树脂组合物以显示与其它树脂成分的优异相容性,加工容易性,机械性能和热稳定性。 通过哌嗪交联的环状磷腈是通过将式(1)表示的环状磷腈化合物与哌嗪交联而获得的,其特征在于,1-环丁基腈化合物的OR基的总数为1-90% 是交联的。 在式(1)中,R是选自苯基,萘基和被一至三个C 1-4烷基取代或未取代的苄基的芳基; m为3〜25的整数。阻燃性树脂组合物包含由热固性树脂,热塑性树脂或其混合物组成的树脂成分和阻燃剂,其中1-80重量份的环状磷腈 对于100重量份的树脂成分,含有作为阻燃剂的哌嗪交联。
