Special Issue Information

Dear Colleagues,

This Special Issue will focus on the design, synthesis and application of novel chemistries being developed by researchers. A first-time report on synthesis flame-retardant additives based on phosphorus, nitrogen, silicone, boron, various metals and their combinations will be the key highlight of this Special Issue. Such flame retardants would be reactive or additive type, and their applications cover all kinds of natural and synthetic polymers. Though the publication of original research papers will be given priority, review articles—especially those outlining different flame-retardant chemistries from their synthesis to application on specific polymers like epoxy resins, polycarbonates, polyolefin, polyurethanes, polyamides, polyesters, polyacrylates etc.—are also welcomed.

Abstract
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 [...] Read more.
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. Full article
