Formation, 3D Structure, and Strength Characteristics of Interpenetrating Polymer Networks Based on Cold-Curing Oligomer-Oligomer Systems

The kinetics of low-temperature formation of interpenetrating polymer networks based on modified epoxy resins and copolymers of unsaturated oligoester resin with oligoether acrylates were studied in relation to the composition of the initial mixture. The influence of the parameters of the three-dimensional structure (cross-linking density, content of lattice points, number of monomeric units in cross-links) on the strength characteristics of the resulting polymer networks was examined, and the best conditions were found for preparing shockproof materials.
