Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.

This plastic bucket has been used as an open-air flowerpot for some years. Photodegradation has made it brittle, causing part of it to break off when the bucket was moved. In polymer chemistry, photo-oxidation (sometimes: oxidative photodegradation) is the degradation of a polymer surface due to the combined action of light and oxygen. [1]
In general, biodegradable polymers break down to form gases, salts, and biomass. [20] Complete biodegradation is said to occur when there are no oligomers or monomers left. [ 20 ] The breakdown of these polymers depend on a variety of factors including the polymer and also, the environment the polymer is in. Polymer properties that influence ...
The researchers say this could mean manufacturers can produce plastics that are easier to break down in sunlight. Sunlight can break plastic down into chemicals that dissolve in water Skip to main ...
Average estimated decomposition times of typical marine debris items. Plastic items are shown in blue. In practice, almost all chemical compounds and materials are subject to biodegradation processes. The significance, however, is in the relative rates of such processes, such as days, weeks, years or centuries.
There are a staggering number of plastics in the world, today, according to a recent analysis — 16,000 plastic chemicals, ... As these chemicals break down in the environment, they can turn into ...
A plastic is considered a bioplastic if it was produced partly or wholly with biologically sourced polymers. A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44]
Many kinds of plastic contain chemical compounds that are indestructible. They do not break down into a nontoxic material that the environment can absorb safely.
