Preparation and physical properties of thermoresponsive biodegradable poly(asparagine) derivatives
New biodegradable and thermoresponsive poly(asparagine) derivatives have been developed. They have a LCST and showed a sol-gel-sol phase transition. The LCST and a sol-gel-sol phase transition temperature could be controlled by the composition ratio of hydrophilic and hydrophobic groups of the polymer side chain.
