Controlling the ratio of antioxidants in plastic can effectively control the start time of plastic degradation. Malaiaka et al. reported the Scott-Gilead system, in which metal dithiocarbamates are used as the antioxidants to react with hydroperoxides to form metal carboxylate complexes and prevent ...
There have been millions of experiments on the degradation of plastics. The reason for that is simple – when a plastic car part, piece of garden furniture or medical device is made, the manufacturer has to be certain that it will last the intended amount of time. What use is a bullet-...
At the same time, the share of packaging materials in the total plastic waste is constantly increasing (Geyer et al., 2017). Plastic waste represents a serious environmental hazard, first of all because of physical deterioration of ecosystems (Sheavly and Register, 2007). Plastic pollution ...
The additive composition can help the degradation of plastic articles, e.g., disposable plastic containers or vinyl packaging containers, manufactured from various kinds of plastic raw materials in a short period of time, and at the same time, can control the time required for the degradation of...
Linear structure undergoes faster degradation of the material than branched. Low molecular weight of a polymer and the presence of easily hydrolyzable chemical groups in the molecule (such as ester, amide, and urea) increase the rate of degradation. Plasticizers or additives used in plastic also ...

Over 8 billion tons of plastic have been produced to date, and a 100% reclamation recycling strategy is not foreseeable. This review summarizes how the mechanochemistry of polymers may contribute to a sustainable polymer future by controlling the degrada
Fig. 1: Time related mass loss of glubam materials. Boxes are colored according to the different median mass loss ratios from five types of glubam. The lower and upper quartiles of mass loss are shown as the bottom and top edges of the box, respectively. The whiskers that extend below an...
Hence, they concluded that the degradation in power was due to the presence of moisture in the delaminated regions of the module, as observed by increased series resistance with time. Also, Adams et al. (2015) believed that the presence of ingressed water at the hole extraction/active layer...
The most apparent outcome of degradation is to shorten the service lifetime of the PU material. More importantly, the degradation of PU elastomers may cause serious issues in certain circumstances. In marine applications, for example, PU elastomers with high flexibility and acoustic transparency are ...
