polymers
Polymers are formed from
monomers as a result of reactions
such as polymerization,
polycondensation.
Due to their valuable properties,
polymers are used in:
Mechanical engineering
Textile industry
Agriculture
Medicine
Automotive

Сomposition of
polymers
The composition of such a molecule usually
includes only 4 elements. These are nitrogen,
oxygen, hydrogen and carbon. These elements
can be combined in various combinations.
Hundreds of thousands of different polymer
substances with unexpected properties can be
made up of them

Properties of polymers
They all have special mechanical properties, due to which they
stand out favorably among other materials.
Different polymers are characterized by:
elasticity
low brittleness
high viscosity at dissolution
mechanical strength
electrical insulation properties

Application of polymers
in construction
Polymers with high strength, ductility and
low thermal conductivity are widely used
in modern load-bearing and enclosing
structures. The main uses of polymers are:
polymer concrete structures, composite
racks, beams and fittings, multi-chamber
frames for double-glazed windows,
glazing made of monolithic and cellular
polycarbonate, and so on.
Polymers are also used in interior wall
decoration. The modern range of
materials intended for finishing the interior
walls of buildings made of polymer
materials is quite wide and diverse:
paints, wallpaper, plastic plates, siding,
decorative plasters and many others.

Advantages and disadvantages of
polymers
Advantages of polymer materials and products:
the ability to accept any color and texture.
a valuable set of properties
the ability of polymers to form thin, durable films
ease of processing polymer materials
Disadvantages of polymer materials and products:
insufficient durability
aging
sensitivity to ultraviolet radiation
low rigidity and surface hardness
creep
the ability to accumulate static electricity.
