The intermolecular forces present in $Nylon-6,6$ are........

As the molecular weight increases,the tensile strength of polymers:

Identify the use of $Buna-N$ from the following:

Given $A = \text{Nylon-}6,6$,$B = \text{Buna-}S$,and $C = \text{Polythene}$. Arrange these polymers in the increasing order of their intermolecular forces (from weakest to strongest).

Match the following:

List-$I$ (Polymer)	List-$II$ (Used in Making)
$A$. Urea-formaldehyde resin	$I$. Safety Helmets
$B$. Glyptal	$II$. Gaskets
$C$. Bakelite	$III$. Laminated sheets
$D$. Nylon-$6,6$	$IV$. Commercial fibres
$E$. Phenol-formaldehyde	$V$. Paints

Correct answer is:

Which of the following statements is $NOT$ true about natural rubber?
