Abstract
Incentive sensing polymers are polymers capable in response to little changes of parameters of a surrounding medium change their properties, they can reversible swell or contract in response to external conditions such as temperature, the solvent nature ionic strength, pH, an electric field and light. Thanks to these properties polymers can be used as systems with controlled selection of medicinal substances, sensors, carriers of insulin, artificial limbs. Water-soluble polymers thanks to activity of macromolecules in a varying degree are show sensitivity to influence of temperature. However, the greatest interest in the practical relation represents heat-sensitive polymers aqueous solutions of which have the lower critical temperature of disolution.
