THERMOSENSITIVE MICROGELS OF POLY-N-ISOPROPYLACRYLAMIDE FOR DRUG CARRIERS--PRACTICAL APPROACH TO SYNTHESIS.

ABSTRACT

The aim of the work is to present the main actual information on the preparation of polymers, derivatives of N-isopropylacrylamide, formed into microgels. The most often used comonomers, crosslinkers, and initiator systems are gathered herein. The known methods of emulsion polymerization and precipitation polymerization are also described, including the application of the surfactants, as well as the surfactant free emul- sion polymerization. Finally, the procedures of lab-scale production of microgel were evaluated in the paper, with special intact on the thermosensitive N-isopropylacrylamide derivatives for application in biomedical field.
