Poly(isobutylene-co-maleic acid) sodium salt
Poly(isobutylene-co-maleic acid) sodium salt (CAS: 39612-00-5) is a cross-linked, hydrophilic copolymer. It exhibits excellent water absorption properties, with a capacity of up to 300 g/g in distilled water, though this decreases significantly in saline solutions. This material is stable up to 250°C and is primarily utilised as a superabsorbent fiber. Its unique characteristics make it suitable for various material science applications requiring high absorbency.
Superabsorbent Fibers
Utilised for its high capacity to absorb aqueous fluids, making it ideal for applications requiring rapid and extensive liquid uptake. The absorption capacity is dependent on the ionic strength of the surrounding fluid.
Hydrogel Development
The hydrophilic nature and cross-linked structure of this polymer make it a suitable component for developing hydrogels with specific absorption and swelling characteristics.
Materials Science Research
Investigated for its properties in advanced materials, particularly in areas where controlled water absorption or hydrophilic surfaces are required. Its thermal stability is advantageous for processing.
