Interpenetrating polydicyclopentadiene/polyacrylate networks obtained by simultaneous non-interfering frontal polymerization

Abstract

Interpenetrating polymer networks made of dicyclopentadiene and methyl methacrylate or tri(ethylene glycol) dimethacrylate have been successfully prepared by non-interfering frontal polymerization. The role of catalyst and free radical initiator relative amounts, as well as of monomer ratio, has been thoroughly studied. The conditions under which a pure frontal polymerization occurs, and the related values of both front velocity and maximum temperature reached by the reaction, are presented and discussed.

UV‐ignited frontal polymerization of an epoxy resin

“…If the amount of dissipated heat is not too great, then a sufficient quantity of energy able to induce the polymerization of the monomer close to the hot zone is provided. The result is the formation of a hot polymerization front capable of self‐sustaining and propagating throughout the reactor 20–36…”

“…In recent years, our group has started the investigation on this matter, paying particular attention to the possibility of finding new chemical systems that are able to bring about FP, such as polyurethanes,30, 31 unsaturated polyester resins,32, 33 polydicyclopentadiene,34 and its interpenatrating polymer networks with polyacrylates 35…”

Frontal polymerization as a convenient technique for the consolidation of tuff

“…Since 2000, our research group has been active in this field [20][21][22][23][24][25][26][27][28][29][30]. Namely, we have studied the application of FP to the synthesis of polyurethanes [20,21], polydicyclopentadiene [22], polyacrylates [23], interpenetrating polymer networks composed of polydicyclopentadiene and polyacrylates [24], polyester resins [25,26] and epoxy resins [27].…”

“…Namely, we have studied the application of FP to the synthesis of polyurethanes [20,21], polydicyclopentadiene [22], polyacrylates [23], interpenetrating polymer networks composed of polydicyclopentadiene and polyacrylates [24], polyester resins [25,26] and epoxy resins [27]. Furthermore, polymer nanocomposites containing polyhedral oligomeric silsesquioxanes [28] and montmorillonite [29] as nanofillers were synthesized.…”

Frontal atom transfer radical polymerization of tri(ethylene glycol) dimethacrylate

“…In particular, the following have been studied: frontal ring opening metathesis polymerization (FROMP) of dicyclopentadiene [11]; the synthesis of polyurethanes [12,13]; the curing of polyester-styrene resins [14]; the production of interpenetrating polymer networks composed of polydicyclopentadiene and polyacrylates [15]; and the consolidation and protection of porous materials (stone, wood, textiles) with applications in the artistic-historical field [16].…”
