  • FLAME RETARDANT COMPOSITIONS, MASTERBATCHES, GLASS FIBER-NYLON COMPOSITIONS AND PREPARATION METHODS THEREOF
    Publication number: 20250197638
    Abstract: A flame retardant composition includes 40-60 parts by weight of phosphonate, 5-15 parts by weight of an organosilicon flame retardant, and 2-8 parts by weight of an inorganic silicon synergist. The phosphonate is prepared by a method including: (1) condensing a compound represented by formula (I) such that some of the compounds form a polymer, giving a partially condensed product; and (2) reacting a rare earth inorganic salt with the partially condensed product to form the phosphonate.

  • POLYLACTIC ACID COMPOSITIONS AND METHODS OF PREPARING THE SAME
    Publication number: 20250122373
    Abstract: The present disclosure provides a polylactic acid composition and a method of preparing the same. The polylactic acid composition comprises a polymeric material and a reaction product obtained by reacting a compound represented by formula (A) with a compound represented by formula (B), the polymeric material comprising polylactic acid, the compound represented by formula (A) being a trimeric phosphazene-based substance, and the compound represented by formula (B) being diamine. The polylactic acid composition is favorable in both flame retardancy and toughness.

  • Use of rare earth amino acid complex, polylactic acid composition and preparation method thereof
    Patent number: 12122894
    Abstract: Provided are use of a rare earth amino acid complex, a polylactic acid composition and a preparation method thereof. The rare earth amino acid complex is formed by complexing a rare earth metal ion with an amino acid; a rare earth element corresponding to the rare earth metal ion is one or more selected from the group consisting of lanthanum, cerium and samarium; and the amino acid is at least one selected from the group consisting of proline, L-phenylalanine, tyrosine and tryptophan.
