The influence of monomer content on the viscoelasticity, water sorption and solubility of experimental fluorinated soft lining materials was investigated. Changes in the viscoelastic properties of the materials were also examined after thermal cycling. Four fluorinated soft lining materials containing different amounts of methoxy diethylene glycol methacrylate (MDGMA) and tridecafluorooctyl methacrylate (13FMA) were prepared. The viscoelastic displacement for specimens containing 13FMA was found to be less than that without 13FMA (p<0.05), and the values tended to decrease with increasing 13FMA content. Reduction of the MDGMA content and addition of 13FMA caused a decrease of water sorption and solubility (p<0.05). Thermal cycling was found to affect the viscoelastic deformation of the specimens without 13FMA and those specimens with relatively large amounts of 13FMA.

“…Debonding by cohesive failure was observed not only before thermal cycling but also after thermal cycling, indicating that the MPTS treatment improved the resistance of the bond to be attacked by moisture. It is noteworthy that the bond strength of the Ti with sandblasting, followed by the MPTS treatment, after thermal cycling (27.9 and 34.7 MPa) is similar to that of a MMA/PMMA resin and the mirror‐finished Ti treated with 0.1 mol % of 10‐methacryloyloxydecyldihydrogenphosphate (MDP) in acetone (37.9 and 38.7 MPa depending on the initiator system for curing) 34. As MDP has been employed for use with non‐precious metals, it is expected that MPTS accomplished a sufficiently strong bond between Ti and the opaquer for practical use.…”

“…Table VI shows the effects of the MPTS treatment on the bond strength between the alloy adherends and the opaquer, showing that MPTS effectively enhanced the bond strength of the Co‐Cr and Ni‐Cr alloys as well as the Au‐Ag‐Pd alloy containing Cu. The tensile bond strengths of MMA/PMMA resin to the Co‐Cr and Ni‐Cr alloys treated with MDP have been reported to be 32.9 and 41.1 MPa after 2000 thermal cyclings,34 respectively, while the bond strength of the respective alloys and the opaquer after sandblasting followed by treatment with an MPTS ethanol solution were 31.2 and 34.6 MPa before thermal cycling (Table VI). Although these two sets of values were obtained after and before thermal cycling, the bond strengths shown in Table VI indicate that MPTS can promote the bond between the alloys and the opaquer to a considerable extent.…”

Adhesion of a cured dental opaquer, which masks metallic appearance and color, to sandblasted Ti aided by 3-methacryloyloxypropyltrimethoxysilane (MPTS) is investigated. The tensile bond strengths of Ti and the opaquer are 43.3 and 45.9 MPa, respectively, when MPTS dissolved in ethanol (6 wt %) and premixed with the opaquer (3 wt %) are applied to the sandblasted Ti surface. Mirror finishing alone and sandblasting alone result in the bond strengths of 1.8 and 21.3 MPa, respectively. After thermal cycling (4 and 60 C for 5000 cycles), the bond strengths of the Ti with sandblasting and the MPTS treatment remain higher than that of the Ti with sandblasting only. Sandblasting and the MPTS treatment effectively promote the adhesion of the opaquer to Ti that rapidly forms an oxide surface layer. The silane-aided adhesion of the opaquer to the sandblasted NiACr, CoACr, and AuAAgAPd alloys attain adhesive strengths of 33.2, 31.9, and 31.6 MPa, respectively.

“…In Figure 2, a strong fluorine resonance by solid state 19 F NMR spectroscopy is shown for the 50% TMPTMP material functionalised by the UV method. The intensity of the peak does not diminish following extensive washing in THF, indicating that the fluorinated acrylate is bound chemically to the surface of the material 28 .…”

Highly porous polymers (polyHIPEs) have been prepared by the photopolymerization of high internal phase emulsions (HIPEs) with varying ratios of thiol and acrylate monomers. The resulting polymers have a nominal porosity of 80%, and are seen to have a well-defined, interconnected pore morphology, with average pore diameters ranging from 30 to 60 µm. The polyHIPE polymers have been shown using a colourimetric (Ellman's) assay to contain residual thiols which are reactive towards a range of (meth)acrylates (hexfluoroisopropyl acrylate, fluorescein O-acrylate and poly(ethylene glycol) methyl ether methacrylate). Functionalization was explored using thermally-and UV-initiated radical-mediated "click" reactions and an amine-catalysed Michael addition reaction. The extent of functionalization was investigated qualitatively and quantitatively using a range of techniques (solid state NMR spectroscopy; FTIR spectroscopy; X-ray photoelectron spectroscopy (XPS); observation of fluorescence); high levels of conversion (up to 90-95%) were observed for the thermallyinitiated radical reaction and the Michael reaction.
