Which class of polymer is Buna-S?
Options:
Answer:
A
Solution:
The mode of polymerisation is classified into:
I. Addition polymers:Polymers are formed by the repeated addition of monomers with double and triple bonds. It is further classified into,
a. Homopolymers:Polymers formed by the polymerisation of a single monomeric species. Examples – Polythene, Polystyrene.
b. Co-polymers:Polymers formed by addition polymerisation of two different monomers. Examples – Buna-S, Buna –N.
II. Condensation polymers: Polymers formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units with elimination of simple molecules. Examples – Nylon 6, 6, Nylon 6.
