Chapter 31: Q3E (page 1039)

Polystyrene is produced commercially by the reaction of styrene with butyllithium as an anionic initiator. Using resonance structures, explain how the chain-carrying intermediate is stabilized.

Short Answer

Expert verified

Resonating structures is:

Intermediate are stabilized by resonance involving phenyl group.

Step by step solution

01

Polystyrene from Styrene

Styrene is the monomer of polystyrene that the polystyrene is formed by the building block of styrene coming together and the reaction is followed by the addition of the nucleophilic which leads to the delocalization of the aromatic benzene ring.

02

Resonating structure of styrene

As styrene contain the one aromatic benzene ring and the alkene group it is an electron-donating group that shows a reaction with the nucleophile like butyllithium and forms the resonating structures as shown below and the stability of the all resonating forms is due to the involvement of the phenyl ring in the delocalization of pi electrons.

Order the following monomers concerning their expected reactivity toward anionic polymerization, and explain your answer:

H2C = CHCH3, H2C = CHC 鈮�N, H2C = CH-C6H5

When styrene, C6H5CH=CH2 , is copolymerized in the presence of a few percent p-divinylbenzene, a hard, insoluble, cross-linked polymer is obtained. Show how this cross-linking of polystyrene chains occurs.

2-Ethyl-1-hexanol, used in the synthesis of di(2-ethylhexyl) phthalate plasticizer, is made commercially from butanal. Show the likely synthesis route.

1,3-Cyclopentadiene undergoes thermal polymerization to yield a polymer that has no double bonds in the chain. Upon strong heating, the polymer breaks down to generate cyclopentadiene. Propose a structure of the polymer.

Epoxy adhesives are cross-linked resins prepared in two steps. The first step involved the SN2 reaction of the disodium salt of bisphenol A with epichlorohydrin to form a low molecular weight prepolymer. This polymer is then cured into a cross-linked resin by treatment with a triamine such as
