“…It can be seen that the opposite effect of water immersion in changes of υ e may be observed. The calculated values are comparable to those presented before in the literature by Shivarkar et al [27]. For unmodified UP the water immersion process caused a slight and negligible increase in the cross-link density, while for both IFR a serious decrease in this parameter was observed, more pronounced for UP/30 LHP.…”

In this paper, the fire behavior of unsaturated polyester resin (UP) modified with L-histidinium dihydrogen phosphate-phosphoric acid (LHP), being a novel intumescent fire retardant (IFR), was investigated. Thermal and thermomechanical properties of the UP with different amounts of LHP (from 10 to 30 wt. %) were determined by thermogravimetric analysis (TG) as well as dynamic mechanical thermal analysis (DMTA). Reaction to small flames was studied by horizontal burning (HB) test, while fire behavior and smoke emission were investigated with the cone calorimeter (CC) and smoke density chamber. Further, the analysis of volatile products was conducted (TGA/FT-IR). It was observed that the addition of LHP resulted in the formation of carbonaceous char inhibiting the thermal decomposition, burning rate and smoke emission. The most promising results were obtained for the UP containing 30 wt. % of LHP, for which the highest reduction in maximum values of heat release rate (200 kW/m2) and total smoke release (3535 m2/m2) compared to unmodified polymer (792 kW/m2 and 6895 m2/m2) were recorded. However, some important disadvantage with respect to water resistance was observed.

“…A somewhat different example in the field of coatings was recently reported by Jain and co-workers. 64 In this case a polyester with only 2 wt% itaconic acid was used as the backbone for an acrylic resin. In detail, the unsaturated double bonds of the polyester were reacted with methyl methacrylate, butyl acrylate and styrene by means of radical polymerization.…”

“…The storage stability of the emulsion decreased when the WP ratio was 1/4. The compatibility issues between WP and polyacrylate might lead to the instability of the emulsion 22 . As is shown in Table 2 and Figure 2, when m (WP)/ m (Ac) was 1/4, the pencil hardness decreased, the water resistance became poor and the water absorption increased.…”

“…The storage stability of the emulsion was not good enough. Shivarkar et al 22 used itaconic acid to synthesize unsaturated polyester and the acrylate monomer is then grafted onto the polyester. The modified acrylic resin also had the shortcomings mentioned above.…”

The high molecular weight polyacrylate self‐emulsifying emulsion with 20% hydroxyl monomer and 50% solid content was prepared. Waterborne polyester was used to modify the acrylate resin. Besides acrylic acid (AA) and methacrylic acid (MAA), poly(ethylene glycol) methyl ether methacrylate (PEGMEMA) was also used as functional monomer to stabilize the polymerization process and improve the properties of the emulsion. The effects of the amount of waterborne polyester (WP), ammonium persulfate (APS), poly(ethylene glycol) methyl ether methacrylate (PEGMEMA), methacrylic acid (MAA)/acrylic acid (AA) monomer ratio, butyl acrylate (BA)/styrene (St) monomer ratio on the molecular weight, particle size, viscosity, storage stability, and cured film properties of the polyacrylate emulsion were investigated. The average molecular weight of the modified polyacrylate was up to about 2.5 × 104 g mol−1. The emulsion remained stable after 6 months at room temperature. Transmission electron microscope (TEM) images showed that the latex particles had core‐shell structure. The films cured with melamine formaldehyde (MF) resin showed excellent water resistance, adhesion, and hardness.
