dc.description.abstract	Star-shaped polymers, consisting of a core and a number of arms radiating from the core, have attracted more attention because of their highly branched structures and unique rheological properties. Star-shaped polymers' unique shape and associated properties such as their compact structure, high arm density, efficient synthetic routes, and unique rheological properties make them promising tools for use in drug delivery, other biomedical applications, thermoplastics, and nanoelectronics among other applications. In this study, the effects of attractive potential on the structure of model single star diblock copolymer using Monte Carlo simulation method have been studied. A coarse grain strategy is adopted for the development of computational tractable models which take explicitly into account the specific architecture and the extended flexibility. Particularly the effect of attractive potential, arm length, number of arms, and temperature has been investigated; and investigate the significant of attractive potential effect on the structural properties (size, shape, distribution of inner monomers and outer monomers) of a star diblock copolymer. The attractive potential is found to have an effect on the radius of gyration (size), the shape parameters (asphericitiy, acylindricity and shape anisotropy) and packing fraction derived from the eigenvalues of gyration tensor. Keywords: star shaped polymer, single star diblock copolymer, Monte Carlo Simulation, Coarse grained model.	en_US
