Step-by-step explanation
(A) Weak Intermolecular Forces are present in polymer of chloro, butadiene.It is a monomer of neoprene which is a rubber(elastomer.).
(B). Hydrogen Bonding is present in NYLON which is a polymer of Hexamethylenediamine and adipic acid. This hydrogen bonding is due to the presence of amide group.
(C) Heavily branched polymer is Bakelite which is polymer of phenol and formaldehyde. It is a crosslinked polymer.
(D) High density polymer(polyethylene) preparation requires and as a catalyst (Ziegler Natta Catalyst)
