Int J Petrochem Sci Eng. 2017;2(7):238-245 238 Abstract Poly (methyl methacrylate-butyl acrylate-acrylic acid)/nano bentonite 34 and Cloisite 20 A composites were prepared through bulk polymerization in presence of BPO (benzoyl peroxide) as initiator. The polymer/nano bentonite composite sheets were molded at 180˚C prior subjecting to the specific mechanical and electrical characterization. Structural, physical and thermal validations were conducted through GPC, FT-IR, XRD and HRTEM and TGA classified techniques. The results of the electrical resistivity and mechanical properties aptitudes signpost step towards a new generation of halogen free insulators for electrical cables according to IEC 60502 and BS7655 standards.
