The network structure model of amorphous and semi-crystalline homopolymer is proposed. It is believed that the polymer is composed of vitrified micro-polymer chain network, microcrystalline polymer chain network, cross-linked polymer chain network and entanglement Link chain network structure.Using the chain group as the deformation and statistical unit, the probability distribution function of chain number and chain end distance of the four kinds of networks is calculated by a combination of statistical mechanics and dynamics, and the homopolymer glass The kinetic theory of the transformation of the isothermal and non-isothermal glass transition kinetic equation and the theoretical characterization of its DSC curve; calculated four kinds of network glass transition viscoelastic deformation free energy and the glassy free energy And the total free energy of the glass transition of the homopolymer network. The static modulus, memory function, relaxation spectrum and dynamic mechanical properties (dynamic viscosity, dynamic modulus and loss tangent) of homopolymer glass transition were obtained. .
