Chapter 30: Question 30.51 (page 1228)

What epoxy resin is formed by the following reaction sequence?

Short Answer

Expert verified

Answer

Formation of prepolymer and epoxy resin

Step by step solution

01

Epoxy resins

The polymer molecules consisting epoxide groups are commonly called by the name polyepoxides. These polymers mainly consist of oxirane rings as the monomer units. There may be other substituents and alkyl chains.

02

Formation of a prepolymer

The hydroxyl group of the first reactant and the chlorine atom of the second reactant are replaced and the oxygen atom helps in connecting both the molecules. The monomer units keep on repeating.

03

Reaction of the prepolymer with ethane-1,2-diamine

The reaction of obtained prepolymer with ethane-1,2-diamine results in the connection of two molecules of the prepolymer. The group becomes NH and it helps in connecting two prepolymers. The reaction is shown below.
