Interpretation:
The monomer unit of poly(vinyl acetate), a polymer in paints and adhesives should be determined.
Concept Introduction:
On the basis of type of polymers, the polymerization reaction can be of two types, i.e., addition polymerization and condensation polymerization. The addition polymerization occurs between monomer units with unsaturated bonds between carbon atoms. For example; polymerization of
Condensation polymerization occurs with those monomers which have some
elimination of small molecules such as H2O, CO, and CO2, etc.

- Using a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40. a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L) b) Calculate the molar absorptivity, a, of the 1645 cm-1 band c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c.
