Abstract

Crosslinker-free poly(n-isopropylacrylamide) (polyNIPAM) particles produced by conventional emulsifier-free heterophase polymerisations contain gels and do not easily and completely disintegrate in water, if at all. These particles, when cooled below lower critical solution temperature (LCST) swell first and then gradually shrink, due to their slow rate of disintegration. We first show that only particles formed using very low monomer concentration, which have a low molecular weight, are fully soluble in water. Then, we describe a seeded semicontinuous route which was designed in order to be able to maintain a low monomer concentration in water in the course of reaction and control the length and location of growing chains. Nanoparticles produced via semicontinuous approach not only disintegrated in water very quickly but also dissolved in water completely as soon as LCST was reached. This finding may also find applications in technologically important processes for dissolution of macromolecules in solvents.
