Photodegradable polymers, agricultural

The major market for photodegradable polymers has been in agriculture and packaging where the major group of polymers used are the polyolefins. In agriculture, the... 

Of the polymers studied the methylated polyamides B and C are both biodegradable and photodegradable. Their use in agriculture are being studied. 

On the more commercial front, the photooxidation of polymers continues to attract attention with a continued special interest in natural materials. Bio- and photodegradable plastics are important for agricultural usage. The same applies to polymer stabilisation where commercial applications dominate significantly with much emphasis on the synergistic behaviour of stabilisers. For dyes and pigments stability continues to be of major concern. 

The photooxidation of polymers on the other hand eontinues to remain at a low profile. Bio- and photodegradable plasties continue to be useful for agricultural usage, although interest here is again minimal. The same applies to polymer photostabilization, where eommercial applieations dominate very much, with emphasis on the practical use of stabilizers. For dyes and pigments, stability continues to be a major issue in so far as this seetion is concerned.
