WebJul 3, 1998 · The worm-like chain model has often been employed to describe the average conformation of long, intrinsically straight polymer molecules, including DNA. The present study extends the applicability of the worm-like chain model to polymers containing bends or sections of different flexibility. Several … WebThis paper describes effects of the flexibility, length, and branching of side chains on the mechanical properties of low-bandgap semiconducting polymers. The backbones of the polymer chains comprise a diketopyrrolopyrrole (DPP) motif flanked by two furan rings and copolymerized by Stille polycondensation wi

WebWhen joined together they will form different variations of polymer chains. A large number of paperclips, preferably of different size and colour. First take a set of paperclips all of the same size or colour. These all represent the same molecule. Joining them together shows how many of the same monomer can be used to form a long, polymer chain.
