This paper considers the preparation of the block co-polymer of poly(ethylene terephthalate) and Poly(butylenes terephthalate). PBT/PET block copolymers were prepared using solid state polymerization and crystallization behavior was studied. The final product of conventional solution to melt polymerization techniques is random co-polymer so we use the solid state polymerization technique to obtain block co-polymer as final product
