Figure 2.24. Kinetic of the change of absorption baunds intensity of CA-film in the process of
irradiation by mercury-quartz lamp. 1 - CA-film without additive, 2 - CA-film with BA additive, 3 -
CA-film with XXXIV additive, 4 - CA-film with XXXV additive.
Durability of polymer has been studied as the criterion of the effect of oligomer and
polymer schiff's base on the mechanical properties of CA-film in the process of ultra-violet
irradiation.
It is known that destruction of solids, specifically polymers, at any loading operation may
be considered proceeding from general ideas on the nature of temperature-time dependence of
strong solids. According to these ideas destruction is the kinetic process developing in the
body under the load. The process of destruction means that the principle of disturbance
summation should be kept. This principle may be expressed by the formula:
S dt/τ[σ(t)] = 1
