Step by step solution

01

Polymers:

Polymers are chemical substances that bear large number of molecules made from simple monomer units.Some examples of polymers are nylon-6,6, wool, cellulose, neoprene, rubber, polystyrene, polyethylene, etc.

02

Poly(vinyl chloride):

Poly (vinyl chloride), also known as PVC is one of the most extensively created synthetic polymer. It contains chlorine atoms in the polymer chain.The shorthand structure of poly(vinyl chloride) is given below.

The reaction of urea [(NH2)2 C=O] and formaldehyde (CH2=O) forms a highly cross-linked polymer used in foams. Suggest a structure for this polymer. [Hint: Examine the structures of Bakelite (Figure 30.7) and Melmac (Problem 30.58).]

Draw a stepwise mechanism for the polymerization of isoprene to gutta-percha using(CH3)3CO-OC(CH3)3as the initiator.

Although chain branching in radical polymerizations can occur by intermolecular H abstraction as shown in Mechanism 30.2, chain branching can also occur by intramolecular H abstraction to form branched polyethylene that contains butyl groups as branches.

a. Draw a stepwise mechanism that illustrates which H must be intramolecularly abstracted to form butyl substituents.

b. Suggest a reason why the abstraction of this H is more facile than the abstraction of other H’s.

Lexan can also be prepared by the acid-catalyzed reaction of diphenyl carbonate with bisphenol A. Draw a stepwise mechanism for this process.

Draw a short segment of each polymer:

(a) Isotactic poly(vinyl chloride);

(b) Syndiotactic polyacrylonitrile;

(c) Atactic polystyrene.
