Description

General description

1,2,3,4-Butanetetracarboxylic acid (BTCA) is utilized as a cross-linking agent and as a building block for the synthesis of specialized polymers for the formulation of resins, polymers, coatings, and adhesives.

Application

1,2,3,4-Butanetetracarboxylic acid (BTCA) can be used as a cross-linking agent:

• To functionalize cotton fabric. BTCA-treated fabric shows improved anti-pilling, wrinkle resistance, and fire-retardant properties.
• To fabricate flexible, free-standing nanocellulose membranes. The cross-linking with BTCA improves water stability and ionic conductivity of membranes.
