TL;DR: In this article, a baseline on degradation mechanism and degradation kinetics for lifetime prediction of polylactide (PLA) in a marine environment was established, where samples were immersed in distilled water for six months at different temperatures (25, 30, 40 and 50°C).

TL;DR: In this paper, a model of water diffusion and its effect on the mechanical properties of carbon fiber reinforced polyamide-6 composite cylinders immersed in sea water for deep sea applications is presented.

TL;DR: In this article, the authors studied changes in the mechanical behavior of polyethylene terephthalate (PET) induced by hydrolysis, especially for high degradation levels, and found that the stress at break decreases linearly with the molar mass, and can be described by a simple mathematical expression.

TL;DR: In this article, the authors proposed and validated accelerated ageing tests to study marine ageing of a silica-filled chloroprene rubber (CR) used for offshore applications, and characterized the ageing consequences using physical measurements (FTIR, solid state NMR) and mechanical testing based on monotonic tension tests.

TL;DR: Due to its morphology, hydrolysis of PHBV in natural seawater is quite slow, and samples were observed to undergo preferentially an enzymatic surface degradation, and increasing the aging temperature in the laboratory promotes the water uptake and causes Hydrolysis.
