A novel star-shaped, cardanol-based bio-prepolymer: Synthesis, UV curing characteristics and properties of cured films

Enhancing the material performance of chloroprene rubber (CR) by strategic incorporation of zirconia

“…The halogenated polymers like CR usually show flame resistance as they provide hydrogen halides which can serve as very good radical scavengers for H and OH radicals. 36 We have theoretically studied the flame retardancy of the synthesised composites by calculating the char yield and LOI (limiting oxygen index) values [43][44][45] (Table 3). The char yield of the filled composites increases from 32% (unfilled compound) to 37-45%.…”

β-Carotene/Limonene Derivatives/Eugenol: Green Synthesis of Antibacterial Coatings under Visible-Light Exposure

“…Indeed, thanks to reactive groups in their structure, bio-compounds can be easily functionalized and turned into polymerizable materials. This is the case of alcoholic and phenolic compounds on which epoxide or acrylate groups can be grafted, as it was shown for example on gallic acid, isosorbide, , or cardanol. − Oleic structures, containing unsaturated carbon chains, can be epoxidized and acrylated via inexpensive large-scale processes. Thus, oils were used as cheap monomers, such as ricinoleic oil, , cashew nutshell liquid, or soybean oil. − The low toxicity of natural compounds allows their use in biomedical applications.…”

Highly Crosslinked Polybenzoxazines from Monobenzoxazines: The Effect of Meta-Substitution in the Phenol Ring

“…Thus, gel content was Finally, the polymers' flame retardancy was calculated from the limiting oxygen index (LOI), defined as the minimum fraction of O 2 in a mixture of O 2 and N 2 that just supports flaming combustion [29]. Char yield of a material can be used to estimate LOI according to the Van Krevelen and Hoftyzer equation (Equation (1)) [29,30]:…”
