Synthesis and characterization of a polyester/styrene resin obtained by frontal polymerization

Abstract

The frontal polymerization technique has been successfully applied, for the first time, to obtain an unsaturated polyester/styrene resin. The effect of the ratio of the two aforementioned components, as well as of the type and amount of free-radical initiator on both front velocity and maximum temperature reached by the front, has been thoroughly studied. The resulting products have been characterized in terms of their thermal and dynamic-mechanical behaviour. A comparison of such products with the corresponding materials obtained by the classical batch polymerization technique has evidenced that frontal polymerization allows to reach a higher degree of crosslinking with respect to batch copolymerization and hence a better thermal and mechanical behaviour.

“…They also investigated the formation of simultaneousinterpenetrating polymer networks [11], the influence of the reactor geometry, the spin modes [8], and the use of a microencapsulated initiator [9,12]. Mariani et al employed FP to prepare unsaturated polyester/styrene resins [13], diurethane acrylates [14], and different kinds of hydrogels [15e18]. Chen et al achieved the FP of vinylpyrrolidone [19], 2-hydroxyethyl acrylate [20], and Nmethylolacrylamide [21].…”

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].…”
