SUPPLEMENTARY NOTES ABSTRACTStyrene and methacrylated fatty acid (MFA) monomers were used as reactive diluents in the vinyl ester resins. The viscosities of these resins were measured as a function of reactive diluent content and type, temperature, and vinyl ester molecular weight to determine the operating window for composite manufacture. The viscosity decreased exponentially with reactive diluent content. Styrene and MFA monomers affected the viscosity in the same manner, but not to the same extent. The viscosities of resins using both diluents were accurately predicted using a logarithmic rule of mixtures from the two-component viscosity functions. The viscosity increased exponentially and predictably as a function of the vinyl ester number average molecular weight. Increasing the temperature decreased the viscosity in an Arrhenius manner. The activation energy for viscous flow decreased linearly as the diluent content increased, but was unaffected by vinyl ester molecular weight, fatty acid chain length, and unsaturation level. Overall, the resin viscosity was modeled as simple functions of the resin temperature, vinyl ester molecular weight, styrene content, MFA content, MFA chain length, and MFA unsaturation level, which are all known quantities for a formulated resin. Therefore, the operating window for various liquid molding operations was predicted for standard DGEBA-based vinyl ester resins and low VOC/HAP resins.

Resin, cure, and polymer properties of photopolymerizable resins containing bio‐derived isosorbide

“…As a result, particulate reinforced composites made through SLA, DLP, or even light‐cured direct ink‐write methods could contain considerably higher solids contents in the IM resins versus that of the commercial Formlabs resins. Based on prior composite resins, we would expect this would equate to a 5–10 wt% increase in filler fraction, which would likely result in ~1 GPa increase in modulus 58 …”

“…Based on prior composite resins, we would expect this would equate to a 5-10 wt% increase in filler fraction, which would likely result in 1 GPa increase in modulus. 58 We have tried to identify suitable reactive diluents for our formulations. As shown in Table S2, all of the tested IM-based resins displayed extremely low viscosities.…”

The effect of impurities in reactive diluents prepared from lignin model compounds on the properties of vinyl ester resins

“…This equation effectively has one fitting parameter, as the viscosity of VE828 at 25 °C is too high for accurate measurements. Based on vinyl ester monomer and resin viscosity measurements at different temperatures and as a function of diluent content for a number of diluents, a viscosity of 6 × 10 7 cP for the pure vinyl ester monomer is reasonable . Thus, the trend in the viscosities as a function of reactive diluent content shown in Figure is simply a function of the differences in the reactive diluent viscosities.…”

“…Based on vinyl ester monomer and resin viscosity measurements at different temperatures and as a function of diluent content for a number of diluents, a viscosity of 6 3 10 7 cP for the pure vinyl ester monomer is reasonable. 26 Thus, the trend in the viscosities as a function of reactive diluent content shown in Figure 2 is simply a function of the differences in the reactive diluent viscosities. Thus, no significant differences in the amount of hydrogen bonding is occurring between VE828:St and VE828:MLMC samples.…”

Tailored Biobased Resins from Acrylated Vegetable Oils for Application in Wood Coatings

“…The GPT molecule is smaller than AVOs' molecules, decreasing and disrupting the intermolecular interactions among the larger AVO monomers [32]. Thus, monomer molecules can slide past one another, reducing the activation energy for viscous flow [33]. The Arrhenius relationship (Equation ( 1)) was used to assess how viscosities changed with temperature.…”
