| Abstract | ||
| Poly(methyl methacrylate) was prepared with different molecular weight by bulk polymerization (M = 0.578 x 105 , 1.28x105 & 1.64 x 105 g/mole). Film of PMMA with TiCl3 salt additive ranged from (1-5%) cast from chloroform solutions onto glass plates (the films thickness was ~ 100μm) . The experimental results show the relationship between electrical properties & Viscosity average molecular weight. (DC conductivity) increased three order of magnitud with increasing molecular weight, the Eac (activation energy) values accordingly decrease as the average molecular weight increase. On the other hand , increased by several orders of magnitude with increasing TiCl3 content and applied temperature ranged from (40-100)0C. The activation energy is also determined and found to decrease with increasing salt content. | ||
