1. Objective 1)
PVA(poly(vinyl alcohol)) is prepared by hydrolysis of PVAc(poly(vinyl acetate)), which is synthesized by emulsion polymerization of vinyl acetate.
2. Theory
1) Monomer 7)
A monomer is an atom or a small molecule that may bind chemically to other monomers to form a polymer. The term "monomeric protein" may also be used to describe one of the proteins making up a multiprote
Measurement of Density
The mass is normally measured with an appropriate scale or balance.
The volume may be measured directly (from the geometry of the object) or by the displacement of a fluid.
Hydrostatic weighing is a method that combines these two.
2. Specific Gravity
It is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference materia
