Are bridged Dopo derivatives flame retardant?
Aleksandra Buczko et al. investigated the flame retardant effects of bridged DOPO derivatives on polyamide 6 (PA6). Their results showed that bridged DOPO derivatives are good components for flame retardant PA6.
Is Dopo a flame retardant?
Synthesis of organophosphorus compounds based on 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and its application as flame retardant have created much attention in the flame retardant community. Various chemical reactions and synthetic approaches are followed to develop numerous derivatives of DOPO.
Are Dopo-based derivatives a flame retardant for epoxy resins?
In summary, the DOPO-based derivatives enhanced the fire retarding performance of epoxy by gas phase-condensed phase flame-retardant mechanism. In conclusion, three kinds of DOPO-based derivatives with multiple phosphorous oxidation states were synthesized and applied as flame retardants for epoxy resins.
Why are Dopo-based derivatives flame-retardant?
The high flame-retardant efficiency of DOPO-based derivatives was ascribed to the synergism between the barrier effect in the condensed phase (proved by the high yield and stability of char residues) and the flame inhibition effect in the gaseous phase (proved by the decreased av-EHC values).
Does a Dopo derivative improve flame resistance?
In this study, a DOPO derivative containing phosphorus and nitrogen in the molecular structure with amino as terminal group (DOPO-NH 2) was incorporated into PLA to improve the flame resistance. The addition of this DOPO derivative on the thermal stability, flame retardancy and mechanical properties of PLA was investigated.
How does Dopo react with benzaldehyde?
In their reported work, they reacted DOPO with 4-hydroxybenzaldehyde (4-HBA) to produce P–C bond, followed by the reaction with aniline using p -toluenesulfonic acid (p-TSA) as catalyst to afford the reactive DOPO-derivative 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-yl- (phenylimino)- (4-hydroxyphenyl)-methane (19) (Scheme 14) .
