Abstract
The invention provides approximately monodispersible random copolymers obtained from monomeric mixtures of 2-ethyl-2-oxazoline with 2-isopropyl-2-oxazoline, production method thereof and 2-isopropyl-2-oxazoline homopolymer obtained by using special initiator. Such polymers exhibit temperature-responsiveness in an aqueous solution within a broad temperature range, and are useful materials in the technical fields of surface chemistry and biomaterials.
