Nitroxide-mediated radical polymerization (NMP) is one of the most important techniques to prepare polymer materials with well-defined molecular structure

and made considerable achievements in the past decades

achieving the controlled/living polymerization of kinds of monomers such as MMA

n

-BA

acrylamide

alkadiene and acrylonitrile

with PDI

<

1.1; and succeeding in producing a significant variety of architectures including block copolymers such as graft

star

and comb structure

etc. Moreover

the combination with photo-initiated technique presented NMP a greater breakthrough

performing control/living polymerization in room temperature

which is with more rapid reactive rate. The recent developments of photo-initiated nitroxide-mediated polymerization had focused on the new photosensitive technique

including intermolecular and intramolecular photosensitization. In this paper

we review the recent achievements of photosensitization applied in NMP and give understanding on the photosensitized mechanism

it would be help to research working deeply in this area.
