The resulting materials exhibit a high degree of structural control (dispersity ≤ 1.08) and can be linked by anionic ring-opening polymerisation with mPEG macroinitiators to form block copolymers. In addition to random copolymers, mPEG-b-POlGE block copolymers in aqueous solution were investigated in particular – with a focus on their thermal behaviour. Reading tip: Functional CoatingsThe “EC Tech Report Functional Coatings” gives you an up-to-date bundle on automotive coatings with articles, videos and other handpicked content. In addition, the copolymers can be further functionalised by means of a thiol-ene reaction. The authors see the developed materials as promising candidates for bio-based polyether systems, particularly in the field of temperature-controlled release systems for active pharmaceutical ingredients.
