The conformation of polymers macromolecules and there changes under the polymer deformation are determine the polymers polarizability change. So, the entropy and internal energy of polymers macromolecules system are change under the deformation. The dependent of internal energy variation by polymer deformation under the temperature are considered in that paper. The polymers with different structure of macromolecules are considered in that paper: polymethyl methacrylate, polyvinyl chloride, ABS plastic, polyvinylidene fluoride. It has been show that the greatest changes of internal energy variation by polymer deformation with temperature increasing correspond to polymers with a branched structure of macromolecules and macromolecules in the form of coils.
