Abstract
Molecular modeling calculations have been used to study the conformati ons of ideal branched ethylene-propylene (EP) copolymers. The simulati on was carried at two temperatures -20 degrees C and 80 degrees C. The results of the simulation were compared with the linear EP copolymers . The total number of monomers were kept at 250 for all the simulation s. The calculation showed the branched polymer to have lower radius of gyration (Rg) compared to the linear chain. This indicates a lower in teraction with the solvent and reduced viscosity for the branched poly mer relative to the linear polymer.
