“…T d 's of the polymer alloys were found to slightly decrease in a linear manner with increasing the mass fraction of the BA‐a. Additionally, T d 's of the obtained alloys were found to be higher than those reported in others IPN systems, e.g., 301–367°C for blocked PU/epoxy [] and 338–341°C for PU/PA [].…”

High‐performance ultraviolet (UV) curable polyurethane acrylate (PUA) coating alloyed with thermally curable polybenzoxazine (PBA) is developed. The hybrid polymer networks of PUA and PBA‐a were prepared by sequential cure methods, i.e., UV cure of the PUA followed by thermal cure of the PBA fraction. The effects of sequential cure were investigated in terms of mechanical, thermal, and physical properties of the resulting polymer alloys. The fully cured PUA/PBA‐a alloy films showed only single glass transition temperature (Tg) suggesting high compatibility between the two polymer networks, possibly of an interpenetrating polymer network type. The storage modulus in a glassy state and Tg of PUA/PBA‐a alloys were found to substantially increase with increasing PBA‐a content. Furthermore, degradation temperature at 10% weight loss of the PUA/PBA‐a alloy films was relatively high whereas the char yield at 800°C was found to increase with a PBA‐a component. Hardness was enhanced, whereas water absorption and water vapor permeation rate of the alloy were suppressed by the incorporation of the PBA‐a into the polymer alloys. As a consequence, the properties of UV curable PUA networks can be positively tailored and enhanced by forming hybrid network with PBA‐a. POLYM. ENG.

“…1 and Table IV). This can be considered as evidence for some mixing of the components in these samples 6, 22, 23. MDSC data also verified that some limited extent of mixing of components has occurred in the blend samples containing 30–50 wt % PMMA (see later Table V).…”

The miscibility of the components in natural rubber-poly(methylmethacrylate) blends for potential use as reinforced rubbers was evaluated using the glass transition temperatures, peak widths of the loss tangent peak at the glass transition and the complex heat capacity data obtained from dynamic mechanical thermal analysis (DMTA), and modulated differential scanning calorimetry (MDSC). In addition, the effect of the poly(methylmethacrylate) content on the dynamic mechanical and the physical properties such as tensile behavior and hysteresis loss was studied. DMTA and MDSC data clearly indicated that the blends were phase-separated. Nevertheless, the glass transition temperature of the natural rubber component in the 30-50 wt % NR/PMMA blends has shifted to higher temperatures compared to the natural rubber treated under the same condition, indicating some limited extent of mixing of components in these blends. The physicomechanical properties including moduli at 100, 300, and 500% and tensile strength of the NR/PMMA blends were determined. Incorporation of PMMA into NR matrix improved the strength properties of the NR/PMMA blends prepared reasonably akin to interpenetrating polymer networks (IPN) polymerization method.

“…The feasibility of acrylated HBPE as a UV‐curable component in dual‐curing automotive formulations has been investigated. The acrylated HBPE oligomer was shown to significantly reduce curing time and improve the mechanical properties and thermostability of the coatings, and its optimal amount seemed to be 75 wt% 65…”

Over the past 16 years, hyperbranched polyesters (HBPEs) based on dimethylolpropionic acid have received much attention due to their unique structural characters, their excellent physical and chemical properties as well as their potential applications in coatings, additives, drug delivery, composites, membrane science and supermolecular chemistry. HBPEs have recently become one of the types of commercialized hyperbranched polymers, and their modifications and applications are focuses of research. This paper reviews the developments in the modifications and applications of HBPEs. Copyright © 2010 Society of Chemical Industry
