Fire retardant polymers: Poly(pyridiniu salt)s containing both phosphine oxide and sulfide (or sulfone) moieties as well as poly(pyridinium salt)s with sulfide or sulfone moieties

Title:

Fire Retardant Poly(pyridinium salt) Polymers with Phosphine Oxide and Sulfide/Sulfone Moieties

Category:

Chemistry

Executive Statement:

Innovative ionic polymers designed to provide high-performance fire retardant properties for diverse industrial applications.

Description:

This technology involves the synthesis of novel poly(pyridinium salt)s containing phosphine oxide and sulfide (or sulfone) groups, created via ring-transmutation polymerization of bis pyrylium salts and phosphine-containing aromatic diamines. These polymers produce high char yields and demonstrate low flammability, making them effective as fire retardants. Additionally, phosphine-containing triamine and phosphazene hexamine monomers serve as fire retardant additives, enhancing safety in coatings, textiles, electronics, and lubricants.

Key Advantages:

  • High char yield and reduced flammability for superior fire resistance
  • Versatile ionic polymer coatings adaptable to various surfaces
  • Effective as additives in textiles, lubricants, and heat transfer fluids
  • Suitable for electrostatic discharge coatings protecting electronic components
  • Environmentally safer alternatives to traditional flame retardants

Problems Solved:

  • High combustibility and toxic smoke generation from common polymers
  • Limited effective and safe fire retardant materials for fabric and electronic applications
  • Need for multifunctional fire retardants suitable for diverse industries
  • Inadequate flame retardancy in lubricants and heat transfer fluids

Market Applications:

  • Fire-resistant coatings for industrial and consumer surfaces
  • Flame retardant textiles and protective fabrics
  • Electrostatic discharge coatings in printed circuit and electronic devices
  • Heat transfer fluids with enhanced fire safety
  • Additives for high-performance lubricating oils
  • Protection for electronic and optoelectronic devices
