The [NH(CH2)6NHCO(CH2)4CO]n is a

Which of the following is not a biopolymer?

Chloroprene is the monomer unit in:

Assertion: Glypal is obtained by condensation polymerization of ethylene glycol and terephthalic acid. Reason: Glyptal is used in the manufacture of fabrics.

Assertion: Bakelite is hard and has high melting point. Reason: Interparticle forces of attraction in it are due to H-bonding.

Assertion: Most of the synthetic polymers are not biodegradable. Reason: Polymerisation process induces toxic character in organic molecules.

Assertion: Teflon has high thermal stability and chemical inertness. Reason: Teflon is a thermosetting polymer.

Assertion: Polytetrafluoroethene is used in making non-stick cookwares Reason: Fluorine has highest electronegativity.

Assertion: Polybutadiene is an example of chain growth polymer. Reason: Copolymerization of butadiene and styrene gives Buna-S.

Assertion: Network polymers are thermosetting. Reason: Network polymers have high molecular mass.
