New Thermo-Sensitive Graft Copolymers Based on a Poly(N-isopropylacrylamide) Backbone and Functional Polyoxazoline Grafts with Random and Diblock Structure
New thermo‐sensitive functionalized graft copolymers characterized by a poly(N‐isopropylacrylamide) backbone and grafts containing 2‐ethyl‐2‐oxazoline and 2‐(2‐methoxycarbonylethyl)‐2‐oxazoline units were synthesized. The conformation transition temperatures of the graft copolymers could be modified...

| description | New thermo‐sensitive functionalized graft copolymers characterized by a poly(N‐isopropylacrylamide) backbone and grafts containing 2‐ethyl‐2‐oxazoline and 2‐(2‐methoxycarbonylethyl)‐2‐oxazoline units were synthesized. The conformation transition temperatures of the graft copolymers could be modified by variation of the molar composition in the side chain, by different side chain structure (random distribution of both oxazolines vs. diblock structure) and by hydrolysis of the methylester to the acid form. Graft copolymers with long functional oxazoline side chains allowed the stabilization of aggregates above the phase transition temperature of the backbone until the LCST of the side chain. The temperature window allowing for the formation of stable aggregates was widened with acid functions in the corona.
Graft copolymers of polyNIPAAm main chain and long side chains of 2‐ethyl‐2‐oxazoline and 2‐(2‐carboxyethyl)‐2‐oxazoline with random or block like character have been synthesized. With the correct composition, these new double‐thermo‐sensitive graft copolymers formed stable micelle like aggregates with acid functions in the over a broad temperature range. |
