The synthesis of PMMA modified p-Cresol resin-nylon 6 blends by the in-situ polymer blending in various proportion is described. These new polymer blends has been characterized by FT-IR, DSC-TGA, SEM, and screened for the hydrophobic, mechanical and dielectric properties. The blended materials exhibit good thermal stability and increased hydrophobic nature. Compressive stress and the strain study show that the blends have improved mechanical property. The frequency dependent dielectric property of the blend has been lowered. Thus, PMMA modified p-Cresol resin-nylon 6 blends could be used as a potential material for the fabrication of electronic device application. © 2018, Springer Nature B.V.
