“…LIPNs have attributes of involving relatively simple synthetic routes with the potential to combine the advantages of thermosets with those of thermoplastics 4, 5. Thus LIPNs have received much attention in both scientific and industrial studies because they can often greatly improve mechanical or other properties of polymers through the unique topological entanglement and interpenetration between networks 6–8. They have prodigious application potentials in plastic modification, rubbers, coatings, damping materials, medical materials, etc 9–12…”

Two latex interpenetrating polymer networks (LIPNs) were synthesized with methyl methacrylate (MMA) and octyl acrylate (OA) as monomers, respectively. The apparent kinetics of polymerization for the LIPNs was studied. This demonstrates that network II does not have a nucleus formation stage. The monomers of network II were diffused into the latex particles of network I and then formed network II by in situ polymerization. It indicates that the polymerization of network I obeys the classical kinetic rules of emulsion polymerization. But the polymerization of network II only appears a constant-rate stage and a decreasing-rate stage. The apparent activation energies (E a ) of network I and network II of PMMA/POA were calculated according to the Arrhenius equation. The E a values of POA as network I (62 kJ/mol) is similar to that of POA as network II PMMA/POA (60 kJ/mol). However, the E a value of PMMA as network II POA/ PMMA (105kJ/mol) is higher than that of PMMA as network I (61 kJ/mol). Results show that the E a value of the network II polymerization is related to the properties of its seed latex.

“…The polymerization techniques include interpenetrating polymer networks (IPNs) or seeded emulsion polymerization. IPNs have received much attention in both scientific and industrial studies because they can often greatly improve the mechanical or other properties of polymers through the unique topological entanglement and interpenetration between networks 15, 17. From the topological point of view, IPNs are closely related to polymer blends and block and graft copolymers.…”

Functional poly[styrene‐co‐(2‐ethylhexyl acrylate)‐co‐(1,6‐hexanediol diacrylate)]/poly[(methyl methacrylate)‐co‐(butyl acrylate)‐co‐(methacrylic acid)‐co‐(diacetone acrylamide)] (PS/PA) semi‐interpenetrating polymer networks (semi‐LIPNs) containing ketone carboxyl groups were synthesized by two‐stage emulsion polymerization, and characterized by Fourier transform infrared, transmission electron microscopy, dynamic light scattering and DSC. A unique feature of the PS/PA semi‐LIPNs is their ability to crosslink and form thermosetting full‐IPN polymers through the reaction of ketone carboxyl and hydrazide in the course of film formation at ambient temperatures. Series of latex particles with various levels of crosslinking density in the PS and PA domain and varied composition of PS/PA LIPNs were obtained. The effects of the LIPN PS/PA composition and the level of crosslinking density in the PS and PA domain on film density, swell ratio, mechanical properties and contact angle with water were investigated. Maximum synergy effects obtained at around 50/50 (PS/PA) in terms of mechanical properties, density and contact angle with water indicate that the maximum degree of interpenetration is obtained at this composition.
