The present invention discloses a PBAT resin composition comprising following components: (a) poly(butyleneadipate-co-terephthalate); (b) iron element; wherein, based on a total weight of the PBAT resin composition, a weight content of the iron element is 1 ppm-500 ppm. By adding iron-containing compounds into the composition and controlling the content of the iron element in a range of 1 ppm-500 ppm in the composition, a speed of reaction of aromatic structure in the PBAT resin under a hot and humid condition can be postponed, so that after the prepared PBAT resin composition is aged in boiling water for 24 hours and 48 hours, a variation of b-value is less than 2. The PBAT resin composition has obviously improved color stability in resistance to boiling water aging.

The invention relates to compositions comprising as component (A) 0.1% to 99.9% by weight of phase II ammonium polyphosphate and as component (B) 0.1% to 99.9% by weight of phase I and/or phase III, IV, V and/or VI ammonium polyphosphate, where the sum total of the components is 100% by weight, and to the use thereof in intumescent coatings.

The present invention generally relates to an eco-friendly wearable article comprising a nutrient complex capable of efficiently able to reduce or eliminate methane gas emission during biodegradation of the article, and a method of making the eco-friendly wearable article containing the nutrient complex. Preferably, the nutrient complex typically comprises anionic sulphate ions and cationic salts of iron(II) and copper(II), thereby facilitating methane oxidation in an anaerobic environment such as a landfill.

The present application relates to a polymer composite capable of being quickly dissolved or dispersed in an aqueous solvent, and a preparation method and an application thereof. The polymer composite includes a polymer capable of being thermodynamically dissolved in water or an aqueous solvent and a dispersant containing an ion capable of coordinating with the polymer. The polymer is selected from the group of a water soluble homopolymer and/or copolymer, in particular, thermogelable amphiphilic copolymer.
