Several other hydrophilic macromonomers including 38–44 have been successfully
applied to the dispersion polymerization [117–122]. These macromonomers
were synthesized by radical polymerization in the presence of appropriate
chain transfer agents, followed by transformation of the end group, as was
previously summarized [1]. Akashi et al. [121] used PNIPAM macromonomer 42
in ethanol and have prepared thermosensitive microspheres 0.4–1.2 µm in diameter
consisting of a PSt core and PNIPAM branches on their surface. The particles
are particularly useful for many biomedical applications. Indeed, the particles
have been reported to flocculate with increasing temperature together
with the change in the light transmittance.
