Prodegradant Additives Effect onto Comercial Polyolefins
, 2019 Prodegradant additives (PDA) came up in the last few decades as a possible solution to the low degradability of polyolefins. PDAs attack polyolefins chains cutting and degrading them to a degree that eventually may allow phagocytosis by microorganisms ...

Functionalized Polyolefin With Photoresponsive Surface
ChemistryEuropeThe introduction of stimulus‐responsive groups can give polymers some material properties that cannot be realized simply by design and synthesis. Polyolefins, due to their nonpolar nature, suffer from poor compatibility with polar materials; however ...

A comparative study of two different methods of sample preparation for polyolefins commonly used in medical devices [PDF]
, 2022 Polyolefins (POs) are currently the most widely used engineering plastics due to their relatively low cost, durability, and ease of processing. A feature such as inertness makes polyolefins suitable for applications such as food packaging and medical ...
