PHENOXYCYCLOTRIPHOSPHAZENE ACTIVE ESTER, HALOGEN-FREE RESIN COMPOSITION AND USES THEREOF |
摘要 |
The present invention discloses a phenoxycyclotriphosphazene active ester, a halogen-free resin composition and uses thereof. The phenoxycyclotriphosphazene active ester comprises at least 65 mol. % of a substance having the following structural formula. The halogen-free resin composition comprises 5-50 parts by weight of a phenoxycyclotriphosphazene active ester, 15-85 parts by weight of a thermosetting resin, 1-35 parts by weight of a curing agent, 0-5 parts by weight of a curing accelerator and 0-100 parts by weight of an inorganic filler. The present invention discloses introducing phenoxycyclotriphosphazene active ester into a thermosetting resin, reacting active esters with thermosetting resins, such as epoxy resin, without producing hydroxy groups, which not only satisfies the requirements on being halogen-free and flame retardancy, but also improves the electrical properties (decreasing and stabilizing Dk and Df) of the system, so as to make non-halogenation of high frequency and high speed substrate materials possible. |
