Abstract
A graft reverse thermal hydrogel which does not show substantial loss of complex viscosity at and up to 20 degrees above the transition temperature upon autoclaving or aging. Other embodiments include the graft reverse thermal copolymer which can be dissolved in water to produce the graft reverse thermal hydrogel, a process for manufacturing the graft reverse thermal copolymer and hydrogel and applications for the stable graft reverse thermal hydrogel.
