聚(对苯乙烯磺酸钠) - Reference Information
| sodium polystyrene sulfonate | sodium polystyrene sulfonate is a water-soluble polymer with unique function, used in reactive emulsifier, water-soluble polymer (coagulant, dispersant, container cleaning agent, cosmetics, etc.), water treatment agent (dispersant, flocculant), sulfur exchange resin (membrane), photo agent (membrane), semiconductor, image film, heat conduction products, etc. Polystyrene sulfonate sodium parameter technical index analysis project technical index average molecular weight (Mw) (5-10)× 104 viscosity (mPa s)(25 ℃) 1-100 sulfate (ppm) ≤ 0.2 pH 1-3 color APHA ≤ 300 solid content solid 20-25% PSSS component PSSS content 20% solubility soluble in water odor no odor appearance Appearance light yellow dilute sticky transparent liquid |
| Use | Poly (styrene sulfonic acid) sodium salt is used as a polyelectrolyte. It can also be used as a conductive and antistatic resin for electrophotographic and electrophotographic substrates. It is applied to reactive emulsifiers, water-soluble polymers (coagulants, dispersants, container cleaning agents, cosmetics, etc.), water treatment agents (dispersants, flocs), sulfur exchange resins (membranes), photo agents (membranes), semiconductors, image films, heat conduction products, etc. |
| solution characteristics | sodium polystyrene sulfonate solution is an efficient ionic electrolyte. It is polymerized from sodium styrene sulfonate monomer. It has good environmental protection characteristics for water-based products. sodium polystyrene sulfonate has the following characteristics: (1) compared with other sulfonic acid series, its toxicity is extremely low; (2) high water solubility; (3) anion electrolytic activation is better; (4) strong flocculation. |
| chemical properties | light yellow liquid, no odor, easily soluble in water. |
