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.

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.
