Beschreibung
Zusammenfassung:	The invention discloses an in-situ polymerization flame retardant, which is derived from the following monomers: diacid monomer A: Al is terephthalic acid, A2 is phosphorus diacid monomer of reactive flame retardant containing aromatic ring, Al + A2 = 100mol%, Al = 50-90mol%, A2 = 10-50mol%; Diamine monomer B: one or more diamine monomers containing 4-36 carbon atoms. The invention obtains a novel flame retardant by in-situ polymerization of phosphorus series reactive flame retardant diacid monomer containing aromatic ring in semi aromatic polyamide oligomer, which has the advantages of no precipitation in semi aromatic polyamide, does not affect other properties of semi aromatic polyamide, and has excellent flame retardant performance.
