Solution
The correct options are A a- p B b- p,q D d-r,s The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units.
Terylene is a condensation polymer. Monomers of Terylene is ethylene glycol and teri-phthalic acid.
Buna-S is formed by the monomeric addition of compound styrene (p) and butadiene (q).
