摘要： The present invention discloses a semiaromatic polyamide resin, a preparation method thereof, and a polyamide molding composition consisting of the same, which consists of following components: (A) 20 to 95 wt % of a PA10T homopolymer derived from 1,10-decanediamine and terephthalic acid; and (B) 5 to 80 wt % of a PA6T homopolymer derived from 1,6-hexanediamine and terephthalic acid. Particularly, (A)+(B)=100 wt %.In the present invention, by adding a certain amount of the PA10T homopolymer into the PA6T homopolymer, a melting point of the PA6T homopolymer can be significantly decreased to be below a decomposition temperature thereof, and thereby a processability of the PA6T homopolymer is improved. The prepared semiaromatic polyamide resin has a decreased melting point, and may be processed normally. The polyamide molding composition consisting of the semiaromatic polyamide resin has a good processability, and has excellent surface properties.

摘要： 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.

摘要： The invention discloses a flame-retardant semi-aromatic polyamide derived from the following monomers: a diacid monomer A: where A1 is terephthalic acid or terephthalic acid and other diacid, terephthalic acid accounts for 50 to 100 mol % of A1, and A2 is [(6-oxido-6H-dibenzo-(c,e)(1,2)-oxaphosphorin-6-ketone)-methyl]-butanedioic acid, A1+A2=100 mol %, A1=90 to 99 mol %, A2=1 to 10 mol %; and diamine monomer B: one or more of diamine monomers containing 4 to 36 carbon atoms. In the present invention, by an in situ polymerization, a specific flame-retardant monomer [(6-oxido-6H-dibenzo-(c,e)(1,2)-oxaphosphorin-6-ketone)-methyl]-butanedioic acid is copolymerized in a semi-aromatic polyamide chain segment, excellent mechanical properties and low water absorption can be obtained.
