Tf. Irzhak et al., A MODEL OF PHYSICAL NETWORK - RELAXATION PROPERTIES OF POLYMERS IN THE RUBBER-LIKE STATE, Vysokomolekularnye soedinenia. Seria A, 39(4), 1997, pp. 671-676
A model of the network of physical bonds was used for the description
of relaxation properties of linear and cross-linked polymers at temper
atures above the glass transition temperature. This model allows one t
o apply the temperature and frequency dependences of the elastic modul
us for estimation of the molecular mass distribution of linear polymer
as well as of the distances between nodes of the polymer network.
