Excellent Stability in Water of Single‐Chain Nanoparticles against Chain Scission by Sonication

Excellent Stability in Water of Single‐Chain Nanoparticles against Chain Scission by Sonication

In this study the superior stability against degradation induced by ultrasound irradiation of water‐soluble single‐chain polymer nanoparticles when compared to their parent precursor polymers is reported, and a loop scission mechanism in support of such behavior is suggested. The enhanced stability...

Zusammenfassung:In this study the superior stability against degradation induced by ultrasound irradiation of water‐soluble single‐chain polymer nanoparticles when compared to their parent precursor polymers is reported, and a loop scission mechanism in support of such behavior is suggested. The enhanced stability against chain scission by sonication in water of single‐chain nanoparticles when compared to their parent precursor polymers is attributed to a loop scission mechanism.
