Do every acrylic hat use –CH₂–CH(CN)–?
Answer (1)
Acrylic fabric or textiles are often made from a polymer known as polyacrylonitrile. The repeating unit in the polymer chain of polyacrylonitrile is derived from the monomer acrylonitrile, which has the chemical structure CH 2 = CH(CN) . When polymerized, the repeating unit in the acrylic polymer chain can be represented as ( − CH 2 − CH(CN) − ) n , where 'n' refers to the number of repeating monomer units.
Not every acrylic fabric is made purely from polyacrylonitrile. Some might contain copolymers, which are polymers that contain two or more different monomer units. This means that while many acrylic fabrics will primarily feature the CH 2 − CH(CN) repeating unit, they might also contain other units for different fabric properties, like softness or elasticity.
However, the primary component of most acrylic fibers is indeed derived from e x t C H 2 − CH(CN) , which essentially forms the backbone of these fibers. This chemical backbone gives the fibers their properties such as strength, light weight, and weather resistance. Therefore, if you are referring to typical acrylic fibers used in hats and other textiles, it is correct to say they generally include this chemical unit.
