Chapter 27: Q35P (page 1210)

Five different repeating units are found in the polymer obtained by cationic polymerisation of 4- methyl-1-pentene. Identify these repeating units.

Short Answer

Expert verified

The answer is,

Addition of carbocations

Step by step solution

01

Cationic polymerization

The polymerisation occurs by forming cation intermediates known as cationic polymerisation. This is a type of polymerisation in which a cation undergoes initiation of the polymerisation reaction by transferring the monomers to the growing end.

02

Explanation

The carbocations undergo the addition to the growing end of the polymer chain.

The five carbocations and addition are shown below.

Addition to carbocations

Draw a segment of polystyrene that contains two head-to-head, two tail-to-tail, and two head-to-tail linkages.

The following two compounds form a 1: 1 alternating copolymer. No initiator is needed for the polymerization. Propose a mechanism for the formation of the copolymer.

Explain why, when propylene oxide undergoes anionic polymerization, nucleophilic attack occurs at the less substituted carbon of the epoxide, but when it undergoes cationic polymerization, nucleophilic attack occurs at the more substituted carbon.

Which polymer is more apt to contain abnormal head-to-head linkages: poly (vinyl chloride) or polystyrene?

Bakelite, a durable plastic used for the casing of early radios and TVs, was the first of the thermosetting polymers. It is a highly cross-linked polymer formed from the acid-catalyzed polymerization of phenol and formaldehyde. Because it is much darker than Melmac, Bakelite’s range of colors is limited. Propose a structure for Bakelite.
