Effects of Confinement on the Kinetics of Formation of Sequential Semi-Interpenetrating Polymer Networks

Formation Kinetics of Simultaneous Interpenetrating Polymer Networks Based on Linear Polyurethane and Poly(methyl methacrylate)

“…Interpenetrating polymer networks (IPNs) are a special type of polymer blend in which two or more cross-linked networks are permanently physically entangled. , IPNs can be classified into two categories: sequential IPNs, , in which one of the components is synthesized in the matrix of another network (for instance, methyl methacrylate polymerizes in a cross-linked polyurethane matrix), and simultaneous IPNs, , which are prepared by simultaneously polymerizing two networks through independent reactions in the same reaction vessel (for example, radical polymerization and step-growth polymerization). Simultaneous IPNs (SIPNs) seem to be more suitable for industrial applications because they can be synthesized more rapidly than sequential IPNs.…”
