Biodegradability of Polymeric Compositions Modified by Amphiphilic Complexes

摘要

The paper discusses the effect manganese (degradation activator) organic complexes have on polyolefin compound biodegradabilities. Samples containing different quantities of the degradation activator were tested by two methods. The first one is testing by composting. The biodegradation process progress was judged by the samples' weight change, as well as by comparing the strain and strength characteristics data. The measurements were performed immediately after the preparation and after 30-, 60-, and 90-days conditioning. The second method is accelerated ageing under the exposure to ultraviolet radiation. The study showed significant organic manganese complexes' effect on polyethylene and polypropylene biodegradability, which is of a greater level for polypropylene.
