General description

Random copolymer of N-isopropylacrylamide with 12 mole % butylacrylate. This copolymer shows LCST at 15 C (lower temperature than PolyNIPAM).

Application

Thermosensitive polymer; can be used to form a hydrogel. Aqueous polymer solution undergoes a phase transition from a soluble to an insoluble state when the temperature is raised to ca. 15 °C.

Storage Class

11 - Combustible Solids

There are many potential applications of 'intelligent' aqueous polymer systems in medicine, biotechnology, industry and in environmental problems. Many of these polymer systems undergo reversible phase transitions--for example, abrupt changes in volume--in response to external stimuli such as temperature, pH

Biomer/poly(N-isopropylacrylamide)/[poly(NiPAAm)] thermosensitive polymer blends were prepared and their application as heparin-releasing polymer coatings for the prevention of surface-induced thrombosis was examined. The advantage of using poly (NiPAAm)-based coatings as heparin-releasing polymers is based on the unique temperature-dependent swelling of these
