Bakelite

Vedclass · Answer

(A) Step $1$: Identify the nature of the given polymers. $PVC$, $Polystyrene$, and $PTFE$ are thermoplastic polymers, which soften on heating and harden on cooling.Step $2$: $Bakelite$ is a phenol-formaldehyde resin. It is formed by the condensation polymerization of phenol and formaldehyde, resulting in a highly cross-linked structure.Step $3$: Because of this cross-linked network, $Bakelite$ cannot be reshaped upon heating, making it a thermosetting polymer.Step $4$: Therefore, $Bakelite$ is the correct answer.

Which of the following is a cross-linked, thermosetting polymer?
