- Copolymers are made by polymerizing two or more different monomers, unlike homopolymers that consist of only one type of monomer.
- Acrylic fibres are a common example of copolymers, while materials like Nylon 6, Nylon 66, and PET are homopolymers.
Acrylic fibre is a copolymer, made by polymerizing acrylonitrile with other comonomers.
On the other hand, Nylon 6 and Nylon 66 are homopolymers, and PET (Polyethylene terephthalate) is also a homopolymer.
Therefore, the correct answer is (C) Acrylic fibre.
