What is Polyethylene Oxide CAS 68441-17-8?
The polyquaternary ammonium salt corresponding to CAS 68441-17-8 is a kind of multifunctional cationic polymer:
High-end electronic manufacturing: As the "invisible operator" of PCB copper plating, it breaks through the bottleneck of micron-level circuit accuracy;
Environmental alternatives: Promote cyanide-free electroplating processes to reduce industrial toxicity risks;
Biocompatibility expansion: Demonstrating the potential for intelligent response in drug controlled-release carriers.
In the future, it is necessary to further optimize the stability of its molecular weight distribution and develop online monitoring technologies to meet the demands of intelligent manufacturing.

Polyethylene Oxide CAS 68441-17-8 Use
(1) PCB Copper plating Additive (Core Application)
Mechanism of action:
Cathodic adsorption: Adsorbed at the cathode (negatively charged) in the electroplating solution, it forms a dynamic barrier, refines copper grains, and improves the uniformity of the coating.
Enhanced deep plating capacity: Activate deposition in low-current areas (such as holes), reduce voids, and improve deep plating capacity (TP value increases by 10-30%).
Synergistic effect: Forms a complex with Cl⁻ (50-100 ppm) to stabilize the plating solution; It is compatible with brighteners (such as SPS) to prevent "charring".
Advantages: Suitable for micron-level precision circuits and can replace the highly toxic cyanide copper plating process.
(2) Water treatment and papermaking industry
Flocculant: It coagulates suspended particles through charge neutralization and is used in wastewater treatment and as a wet strength agent in papermaking.
Biocide: Cationic groups destroy the cell membranes of microorganisms and are used to inhibit bacteria in circulating cooling water systems.
(3) Personal care products
Antistatic agent: Added to shampoo and conditioner, it reduces static electricity in hair and improves its combability.
Preservative enhancer: Compounded with ethylhexylglycerin to enhance the efficacy of the cosmetic preservative system.
(4) Biomedical materials
Drug carrier: As a positively charged polymer, it is used to construct hypoxia-responsive drug conjugates (such as poly N-oxide) to enhance tumor penetration.

Polyethylene Oxide CAS 68441-17-8 safety
Toxicity: Low acute toxicity (oral LD₅₀ > 2,000 mg/kg in rats), but irritating to the eyes and respiratory tract.
Protective measures:
Wear impermeable gloves, goggles and gas masks when operating.
Avoid contact with high temperatures (>60°C) and strong oxidants to prevent decomposition and gas production.
Storage: Keep sealed in a cool and well-ventilated place, away from fire sources.
