Question
Chapter 26, Problem 26.31SP
(a)
Interpretation Introduction
Interpretation:
The structures of poly (vinyl acetate) and poly (vinyl alcohol) are to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition
(b)
Interpretation Introduction
Interpretation:
An explanation to predict that the poly (vinyl acetate) is polyester as vinyl acetate is an ester is to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition polymers. These polymers are made, when some alkenes undergo chain growth polymerization by some initiator.
(c)
Interpretation Introduction
Interpretation:
An explanation corresponding to the given statement that hydrolysis does not destroy the poly (vinyl alcohol) polymer is to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition polymers. These polymers are made, when some alkenes undergo chain growth polymerization by some initiator.
(d)
Interpretation Introduction
Interpretation:
An explanation corresponding to the given statement that the poly (vinyl alcohol) is made by given circuitous route rather than the polymerisation of vinyl alcohol is to be stated.
Concept introduction:
The poly (vinyl acetate) and poly (vinyl alcohol) are examples of addition polymers. The poly (vinyl acetate) is converted to poly (vinyl alcohol) by a basic hydrolysis of the ester groups.

Students have asked these similar questions
Which of these is a requirement of monomers in order to undergo addition polymerization?
a. The presence of an oxygen atom.
b. The presence of a carbon to carbon double bond.
c. The presence of a carbon to carbon triple bond.
d. The presence of a lone pair.
Poly(vinyl alcohol), a hydrophilic polymer used in aqueous adhesives, is made by polymerizing vinyl acetate and then hydrolyzing the ester linkages. Vinyl acetate is an ester. Is poly(vinyl acetate) therefore a polyester? Explain.
7. When asymmetric alkenes polymerize (such as chloroethene to produce PVC), the pendant group like
chlorine can be arranged in different ways. An arrangement in which the -Cl groups are arranged on
the same side of the polymer chain is called a(n) ,
a. Atactic
b. Isotactic
arrangement.
c. Syndiotactic
d. Sporadic
8. Kevlar is a type of polymer which has a great resistance to tear. Its application includes its use in making
bulletproof vests and radial tires. The two monomers used to make Kevlar are the following:
H
H
H-O-
c-0-H
H-N-
-N-H
Monomer One
Monomer Two
When these two monomers join
a. A molecule of CO2 will be eliminated and an ester linkage will form
b. Nothing will be eliminated and the two monomers will be linked through a hydrogen to hydrogen
bond
c. A water molecule will be eliminated and a peptide linkage will be formed
d. Nothing will be eliminated. The two monomers will be linked by a carbon-carbon bond.
