Evaluation of benzaldehyde and benzophenone derivatives as accelerators in NR Introduction In spite of the fact that some organic compounds used as accelerators are added in small amounts (1-2 phr), [...]

AbstractUnsaturated polyester based on poly(ethylene, 1,2, propylene ma-leate-phthalate-adipate) was synthesized and used with the styrene monomer as a binder to produce polymeric basalt composites (PBC). The physical properties of the styrenated polyester resin (SP) were determined. Because the aggregate type and composition do affect the durability properties of the composites, the minerological, textural, and chemical composition of the basalt Filler were studied. The mix design for the PBC systems was optimized for workability, strength, and economy. The optimum composition was 10wt% resin and 90wt% oven-dried basalt.The mechanical and durability properties of the prepared PBC have been investigated. The physical, mechanical, and thermal properties of the composites appear to be satisfactorily good. Excellent chemical resistance to most chemical environments was also noted. The dielectric constant (ε′) values indicated that the use of basalt as a filler enhances the electrical characteristics of the PBC as insulators as compared to the SP resin. Obviously, the obtained PBC would be excellent candidates for several potential applications.
