On the basis of the model "polymer chain in an array of obstacles" the influence of the topology effects on the dynamics of concentrated polymer systems is investigated theoretically. The 1 /z-expansion (where z is the coordinational number of the lattice of obstacles) is proposed for this problem.

This article describes the collisional dynamics (CD) method adapted for molecules with geometrical constraints within a description using Cartesian coordinates for the atoms. In the CD method, stochastic collisions with virtual particles are included in usual molecular dynamics simulations to couple
Semi-interpenetrating polymer networks (semi-IPNs) were prepared from linear polyurethane (PUR) and polycyanurate (PCN) networks. Wide-angle X-ray scattering measurements showed that the IPNs were amorphous, and differential scanning calorimetry and small-angle X-ray scattering measurements suggeste
