Question

A synthetic fibre is also a chain of small units joined together. Each small unit is actually a chemical substance.Many such small units combine to form a large single unit called a polymer. The word ‘polymer’ comes from two Greek words; poly meaning many and mer meaning part/unit. So, a polymer is made of many repeating units. Plastic is also a polymer like the synthetic fibre. All plastics do not have the same type of arrangement of units. In some it is linear, whereas in others it is cross-linked. Since plastic takes several years to decompose, it is not environment friendly. It causes environmental pollution. Besides, the burning process in the synthetic material is quite slow and it does not get completely burnt easily. In the process it releases lots of poisonous fumes into the atmosphere causing air pollution. Q2a). Polymers are made up of small units called 1 point Captionless Image .

(a) layers (b) molecules (c) cells (d) monomers​

Answer 1

Answer:

monomers when monomers join they make polymer plastic us made by a monomers ethylene and propylene
