Photosensitizing action of complex compounds of transition-metal salts with aromatic nitrogen-containing vinyl monomers
Production of photosensitizers degradation of high-pressure polyethylene (HPPE) and its technological wastes is of great importance for solving the problem of development of polymers having controllable life. By introducing chemical additives (sensitizers) into ethylene polymers it is possible to obtain photodegradable films (PDR). After a certain service life PDR disintegrate under atmospheric conditions into small fragments, which are then destroyed by soil microorganisms. This obviates the laborious operation of removal of the films from fields and at the same time solves the urgent problem of environmental protection. In order to extend the range of photosensitizing additives for degradation of HPPE, the authors have studied aromatic nitrogen-containing vinyl monomers and their complexes with iron and cobalt chlorides. The properties of these complexes are given in Table 1. The tests were carried out in comparison with the most effective photosensitizer of polyethylene degradation, ferralin (VIII). It was shown that an iron-containing complex compound of the quinoline series has higher photosensitizing activity than the corresponding cobalt complex.
