Descripción

General description

Acrylonitrile is commonly used as a monomer which belongs to the class of unsaturated nitriles. It serves as a key monomer in the production of various polymers and copolymers with desirable properties. Acrylonitrile is commonly employed in the production of acrylic fibers, which are known for their softness, strength, and excellent thermal and chemical resistance. One of the primary applications of acrylonitrile is in the manufacturing of acrylonitrile-butadiene-styrene (ABS) copolymers. ABS is a versatile and highly durable plastic widely used in automotive components, appliances, electronic enclosures, and consumer goods. The addition of acrylonitrile to the copolymer enhances its heat resistance and impact strength, making ABS a highly sought-after material.

Application

El acrilonitrilo se usa en la fabricación de fibras acrílicas, resinas (acrilonitrilo butadieno-estireno, estireno-acrilonitrilo y otras) y cauchos de nitrilo (butadieno-acrilonitrilo).

Acrylonitrile can be used as a monomer:

• In the preparation of the 3D-printed polymer material, Acrylonitrile Butadiene Styrene (ABS) which is a commonly used engineering thermoplastic known for its high strength, durability, and heat resistance. It serves as a suitable substrate for a wide range of applications, including in the medical field, compatible manufacturing processes, injection molding, blow molding, and extrusion.
• In the copolymerization with lignosulfonate to develop a carbon fiber precursor. This copolymer can serve as a precursor material that undergoes further thermal treatment to produce carbon fibers.
• To synthesize acrylamide grafted acrylonitrile copolymer membranes, which serve as a support matrix for the immobilization of cellulase enzymes.
