Studying the influence of pH and the temperature of the environment to viscosity of water solutions, swelling kinetics and collapse of cross-linked polymers and copolymer on the basis of natural ox acids there are founded the presence of pH and heat-sensitive qualities. It is revealed that the existence of polymers as a form of amides and as well as carboxyl groups leads to the appearance of a unique quality of having a little interval of temperature of two critical mixed temperatures
