## Abstract Poly(methyl methacrylate) (PMMA)βclay nanocomposite (PCN) materials were synthesized through __in situ__ intercalative polymerization. A cationic surfactant, [2(dimethylamino)ethyl]triphenylphosphonium bromide, was used as an intercalating agent with pristine Na^+^βmontmorillonite (MMT)
Poly(viny1 formal) films have been grown from solution. The dielectric properties of the films have been studied in the frequency range 100 Hz to 1 MHz at temperatures from 300 K to 450 K.The plots tan 6 versus temperature show two relaxation peaks which are discussed in terms of the molecular struc
