Question

Identify the type of polymer.
(i) - A - A - A - A - A - A-
(ii) - A - B - B - A - A - A - B - A –
Option
A.(i) Homopolymer, (ii) Copolymer
B.(i) Natural polymer, (ii) Synthetic polymer
C.(i) Linear polymer, (ii) Branched polymer
D.(i) Fibre, (ii) Elastomer

Answer 1

Hint:A polymer is a liquid or material made up of several repeated subunits that make up very large molecules, or macromolecules. Both synthetic and natural polymers play important and pervasive roles in daily life due to their wide range of properties. Polymer chemistry is a branch of chemistry that studies polymers and macromolecules' chemical composition, structure, and chemical and physical properties.

Complete answer:
- A - A - A - A - A - A-
Homopolymer:
A homopolymer is formed when only one kind of monomeric unit participates in the formation of a polymeric matrix. A homopolymer is a sequence of monomer units (mers) that are all the same.
A homopolymer plastic is one that is made from a single monomer polymerized. Polystyrene, for example, is a homopolymer since it is made entirely of styrene monomer residues. The following are few examples of homopolymer thermoplastics used in injection moulding: Polypropylene is a type of plastic.
Vinyl chloride units make up the homopolymer polyvinylchloride (PVC). Polypropylene is made up of propylene units that are repeated.

Copolymer:
A copolymer is a polymer made up of more than one monomer species. Copolymerization is the process of polymerizing monomers into copolymers. Bipolymers are copolymers formed by the copolymerization of two monomer species. Terpolymers and quaterpolymers are polymers made up of three and four monomers, respectively.
Since copolymers are made up of at least two kinds of constituent units (also known as structural units), they may be categorised according to how these units are organised in the chain. A single main chain characterises linear copolymers, which involve alternating copolymers, statistical copolymers, and block copolymers. Branched copolymers are made up of a single main chain and one or more polymeric side chains, and they can be grafted, star-shaped, or have other shapes.

Note:
Polymerization is a chemical reaction in which very small molecules, known as monomers, join to form a very long chainlike or network molecule, known as a polymer. The monomer molecules may be identical or could reflect two, three, or even more distinct compounds.
