Title
(EN) RECONSTITUTABLE REVERSE THERMAL GELLING POLYMERS
Abstract
(EN)
Biodegradable and bioabsorbable block copolymers  which can be in the form of solid powder or powder wax compositions that can be easily reconstituted into an aqueous polymer solution and exhibit reverse thermal gellation properties upon exposure to elevated temperatures  are provided. Methods of making using these copolymers are also provided.
