“…The probe tack test has been extensively used to characterize Pressure Sensitive Adhesives (PSA) [32][33][34]. A PSA (which is commonly made of thermoplastic polymers) is usually considered as good if it can form a strong bond with a substrate over a short time, and dissipate a large amount of energy during debonding.…”

a b s t r a c tIn this work, we aimed to characterize the energy of adherence of nanoscale structured epoxy adhesives Diglycidyl ether of bisphenol-A/Methylene-diethylaniline (DGEBA/MDEA) induced by phase separation triblock copolymers Poly (Methacrylate de Methyl)-b-Poly (Butyl Acrylate)-b-Poly (Methyl Methacrylate) (PMMA-b-PBA-b-PMMA) at gel state by a probe tack test, which is an original use of this kind of test for thermoset adhesives. For a set of mechanical parameters (probe's roughness, contact time, contact pressure and debonding velocity), we measured the energy of adherence for both neat and filled adhesives. The probe tack test was performed at different steps of gelation. We compared the behavior of the adhesives and evaluated the dissipation contribution to the energy of adherence of the adhesives during the test. We finally discussed the nanoparticles' influence on the competition between cavitation and fibrillation. We report that the addition of nanoparticles leads to an overall improvement of the energy of adherence, with a significant increase of the dissipation contribution to the energy measured.

“…As consequence methyl radical is obtained, which present the advantage that is less esterical hindrance compared with Cumyloxi radical. Wu et al [17], Ellul et al [19] report the same behavior and that polystyrene characteristic peaks (1601, 1492, 1450, 699 and 540 cm -1 ) remain with not significative change. The same analysis was carried out for adhesive formulations E1-R2, E2-R1 and E2-R2, with different DCP content, and a similar behavior was observed for these 3 peaks at 3400, 1725 and 724 cm -1 .…”

“…It is possible identify signals at 966, 911 and 721cm -1 attributed to out-of-plane bendings of γ(=CH) trans, ω(=CH2) vynil and γ(=CH) cis groups respectively, present in polybutadiene domains Those peaks decrease with time which is associate to crosslinking that occurs in double bonding. In the other hand, typical signals from polystyrene domains (1601, 1492, 1450, 699 and 540 cm -1 ), remain without significative changes [17,18]. That is indicative that crosslinking reaction carries out preferably in double bonds of polybutadiene domains.…”

Adhesion refers to a complicated set of interconnected phenomena that is not easy to understand, and by means several semi-empirical tests try to be predicted the strength of an isolated adhesive joint or the strength of a more complex structure, such a laminate, of a fiberreinforcer of particle-filled composite [2]. Adhesives are classified according with common characteristics to facilitate their understanding and use, although no one classification is universally recognized. Classifications include source, function, chemical composition, physical form and application. Within the most used adhesive are natural or synthetic rubber-based materials, usually due its good properties. Based solvent technology in adhesive is one of the most used for wood industry, mainly Polychloroprene, which has high temperature resistance and good paste strength. However, for halogenated compounds generated and for marketing strategy, this material is intended to be replaced by Styrene-Butadiene rubber (SBR) and Styrene-Butadiene-Styrene (SBS) copolymers, and Styrene-butadiene-Ethylene-Styrene (SEBS).

“…Styrene-butadiene-styrene block copolymer (SBS), one of the most productive thermoplastic elastomers (TPE), has been used in various domains, such as pressure-sensitive adhesives [1,2], footwear, asphalt modifiers [3][4][5][6] and coating because of its good balance between mechanical properties and favorable processability. But the high inflammability of SBS imposes restriction on its application in some high-end fields.…”

The effects of fullerene (C 60 ) and aluminum hydroxide (ATH)/C 60 combination on the thermal stability, flame retardancy and mechanical properties of styrenebutadiene-styrene block copolymer (SBS) were investigated. Adding small amount (0.5-2 mass%) of C 60 into SBS matrix raised the initial decomposition temperature of the composites slightly, while C 60 alone had little influence on the flame-retardant behavior. In SBS/ATH/C 60 system, however, the addition of C 60 significantly improved the UL-94 vertical combustion grade and limiting oxygen index. The total content of the flame retardant in SBS/ ATH/C 60 system (56 mass%) was lower than that in SBS/ ATH system (60 mass%) when UL-94 reached V0 level. Consequently, the adverse effects on the mechanical properties due to the high level of flame-retardant loading reduced. Meanwhile, the data obtained from cone calorimetric test indicated that C 60 can not only reduce the heat release rate, but also raise the char residue of SBS/ATH composites.
