Beschreibung
Zusammenfassung:	The invention discloses an in situ polymerized flame retardant, derived from the following monomers: a diacid monomer A: where A1 is terephthalic acid, A2 is a phosphorus aromatic ring-containing reactive flame-retardant diacid monomer, A1+A2=100 mol%, A1=50 to 90 mol%, A2=10 to 50 mol%; and a diamine monomer B: one or more of diamine monomers containing 4 to 36 carbon atoms. In the present invention, a novel flame retardant is obtained by in situ polymerization of the phosphorus aromatic ring-containing reactive flame-retardant diacid monomers in semi-aromatic polyamide oligomers, which has advantages of no precipitation in the semi-aromatic polyamide and no influence on other properties of the semi-aromatic polyamide and has an excellent flame-retardant property.
