LABORATORY WORK №. 8

Reception of polymer materials and study of their
properties

Purpose: to study the main classes of
macromolecular compounds, their structure, methods of
obtaining, properties and uses.

Reagents and equipment:

benzene, ethanol, phenol, urea, oxalic acid, phthalic
anhydride, glycerol, 35-40% solution of methanal
(formalin), 80% solution of acetic acid (ethanol), 25%
ammonia solution, chloride acid (concentrated ), glasses,
test tubes, filter paper, a piece of plywood, a water bath.
