Kinetics of the collapse and aggregation behavior of a new thermoresponsive polymer - poly(methoxy diethylene glycol acrylate)

DOI

We wish to investigate new, micelle-forming block copolymers containing a new thermoresponsive block, poly(methoxy diethylene glycol acrylate) (PMDEGA), and polystyrene end blocks. This polymer cannot form hydrogen bonds with itself, in contrast to the often investigated PNIPAM. The focus will be on the kinetics of the collapse and aggregation behavior during a temperature jump across the cloud point (~35-40°C) with the focus on (i) the role of bridging between micelles, (ii) the collapse of the micellar shell and the subsequent aggregation of the collapsed micelles, and (iii) the thermal stability of the micellar core. Real-time SANS with a time resolution of 0.1 s will allow us to characterize these issues and relate them to the peculiar mechanical properties. We will compare the results to the ones obtained by us previously on P(S-b-NIPAM-b-S).
