Final answer:
Synthetic polymers like nylon and vulcanized rubber, as well as natural polymers like starch and cellulose, can be used to make thread or rope.
Step-by-step explanation:
Thread or rope can be made from both synthetic and natural polymers. Some examples of synthetic polymers that can be used to make thread or rope are nylon and vulcanized rubber. Nylon is a strong and durable polymer that is commonly used in the manufacturing of ropes, while vulcanized rubber is elastic and flexible, making it suitable for applications like bungee cords and elastic ropes.
On the other hand, some examples of natural polymers that can be used to make thread or rope are starch and cellulose. Starch is derived from plants and can be spun into thread or used as a binder for natural fibers to make ropes. Cellulose, which is found in the cell walls of plants, is also a common material for making ropes due to its strength and abundant availability.
