View All Manufacturers & Suppliers of sodium polystyrene sulfonate API with Drug Master Files (DMF), CEP/COS, Japanese DMFs, Written Confirmation (WC) details listed on PharmaCompass.com Sodium Polystyrene Sulfonate is a potassium ion exchange resin composed of benzene-diethyl polymer with ethenyl-benzene, sulfonated, sodium salt.

- Mechanism of Action & Protocol. The resulting sulfonated polystyrene-functionalized SWCNTs (SPS-SWCNTs) were found to be pH responsive, forming homogeneous solutions in water at pH values between 3 and 13. towards polystyrene which content aromatic compound. Administered as an oral suspension, sodium polystyrene sulfonate lowers serum potassium levels by exchanging its sodium ions for potassium ions.

Sodium styrenesulfonate (NaSS) is a highly reactive vinyl monomer containing a hydrophilic sulfonate group. NaSS is widely used to … 2–4 The commercial suspension is a brown viscous suspension containing 25 g of resin per 100 mL. Calcium polystyrene sulfonate KMP-Ca 37286-92-3 Calcium polystyrene sulfonate [JAN] Calcium salt of sulfonated styrene polymer Benzenesulfonic acid, ethenyl-, homopolymer, calcium salt UNII-HUI2S00793 HUI2S00793 Appearance : Golden Brown fine powder Odor : No specific odor Taste: Characteristic taste Solubility : Practically insoluble in water Functional Group : - SO3H (Sulphonic) Ionic Form : Sodium (Na+) Water (By KFR) : NMT 10.0% Limit of Ammonium Salts : Negative to Red litmus Particle Size : PoRetained Over BSS 100 # : NMT 1% (150 µm) Sodium Contents (By A.A.S.) However, such fibers suffer in terms of dimensional stability due to high water uptake at elevated humidity. Sigma-Aldrich Online Catalog Product List: Poly(styrenesulfonate) (PSS) Solubility: Practically insoluble in water and in 96% ethanol. Polystyrene sulfonate (PSS), a highly conductive polymer, is commonly used for solar films.

Polysciences Asia Pacific, Inc. 2F-1, 207 DunHua N. Rd. Poly(sodium 4-styrenesulfonate) average M w ~70,000, powder Synonym: PSS, Poly(4-styrenesulfonic acid) sodium salt CAS Number 25704-18-1 Linear Formula (C 8 H 7 NaO 3 S) n MDL number MFCD00084449 NACRES Search term: "polystyrene sulfonate" Compare Products: Select up to 4 products. In addition, PSS is also useful for the treatment of hyperkalemia [32] . Typical Specifications of Calcium Polystyrene Sulfonate: Characteristic: A cream to light brown fine powder, free from foreign particles. 1%) levels the solubility behavior of the SSS copolymers and the sulfonated polystyrenes were similar. Calcium polystyrene sulfonate is used to treat hyperkalemia in patients with chronic kidney disease (CKD).

In this . Benzene as aromatic substrate in polystyrene is attacked by sulfur trioxide and produced polystyrene sulfonic acid. Poly(3,4-ethylenedioxythiophene) (PEDOT or PEDT; IUPAC name poly(2,3-dihydrothieno[3,4-b][1,4]dioxane-5,7-diyl)) is a conducting polymer based on 3,4 … Sodium polystyrene sulfonate (the sodium salt of sulfonated styrene copolymer) is a cream-colored to golden brown odorless tasteless fine powder.

Asia Pacific Sales and Distribution. Properties. At low (ca. This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources.Unsourced material may be challenged and removed. However, poor solubility of PEDOT can be overcome by doping polystyrene sulfonate (PSS) into EDOT to make PEDOT:PSS composite material. Significant advantages of NaSS as compared with other monomers are low toxicity and high thermal stability.

However, at higher sulfonate levels the solubility behavior in different solvents and the dilute solution viscometry were significantly different for the two systems. Calcium polystyrene sulfonate is an ion-exchange resin used for reducing blood levels of potassium. Identifications: 1) The IR spectrum of the sample should be concordant with reference spectrum of Calcium Polystyrene Sulphonate BP grade.

Sodium Styrenesulfonate.

2,3 Each gram of the cationic exchange resin exchanges between 110 and 135 mg (between 2.81 and 3.45 mEq) of potassium. The degree of polystyrene sulfonation was varied from 20 to 34 mol%, and was found to be directly proportional to the aqueous solubility of the material. 2 Electrospun nanofibers of highly sulfonated polystyrene (IEC ∼ 4.8 mequiv/g) might be good candidates for use in ion exchange applications because of their ability to form continuous, highly conducting pathways for cation transport. Taipei, Taiwan 10595 (886) 2 8712 0600 (886) 2 8712 2677 fax info@polysciences.tw

electrophilic aromatic substitution, sulfur trioxide is the electrophile generated from concentrated sulfuric acid (or fuming sulfuric acid) when its heated. PEDOT:PSS is a mixture of two ionomers wherein one is made of sodium PSS
