Question 8
1 / -0

Which of the following is a step-growth polymer?

A
Styrene

B
Nylon-6,6

C
Teflon

D
Rubber

Solution

Step-growth polymerization refers to a type of polymerization mechanism in which bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers and eventually long chain polymers.

Nylon-6,6
Question 9
1 / -0

Which among the following is a step growth polymer?

A
Polyether

B
PVC

C
Buna-S

D
Dacron
Question 10
1 / -0

The substance used for coagulating rubber from latex is :

A
Ethanol

B
Ethanoic acid

C
Both

D
None of these

Solution

Ethanoic acid is an organic acid. It Ionizes in water to produce hydrogen ions. The positive hydrogen ions help to neutralise the negatively-charged rubber particles, allowing the latex to coagulate.

Hence, option B is correct.
