Description

Application

PolyNIPAM is a stimuli-responsive polymer. The low PDI means that the distribution of chain lengths is narrow which will typically lead to better reproducibility. This polymer for development of thermosensitive coated micro/nano materials, including thermoresponsive polymeric drug delivery systems.

Thermosensitive polymer, can be used to form a hydrogel. Aqueous polymer solution undergoes a phase transition from a soluble to an insoluble state when the temperature is raised to ca. 32 °C.
