  In this article we introduce MARTINI model of a widely used thermoresponsive
polymer, Poly(N-isopropylacrylamid)e. Our model takes into account polymer's
stereoregularity (i.e. tacticity). We highlight the effect of changing the
polarity of coarse-grained particles comprising the polymer on its ability to
exhibit a temperature-dependent coil-to-globule transition. Our approach allows
to study the behavior of thermoresponsive polymers at large time and length
scales.
