4) In this research, an acrylic latex with a modulus that highly depends on temperature was dried both just above and just below its MFFT.
Table 1 shows the total number of errors and mean latency to the first response on the MFFT for each subject.
For all participants, testing began with the MFFT followed by the computer-administered analogies and fill-in-the-blank tests.

As described in the experimental section, a series of acrylic polymer dispersions was synthesized based on the same MMA/nBA ratio (target MFFT around 0[degrees]C) and same surfactant.
With ethylene incorporated directly into the polymer backbone, VAE resins possess inherent internal plasticization and can offer a lower MFFT without the need for additional solvents or plasticizers, making them an excellent choice for low-VOC coatings, explains Shawn Daniel, a scientist with Arkema Coating Resins.
