MIXTURES OF RIGID AND FLEXIBLE NEMATOGENIC POLYMERS

Title: MIXTURES OF RIGID AND FLEXIBLE NEMATOGENIC POLYMERS
Abstract: We consider three systems containing rigid and/or flexible main-chain polymers: mixtures of a rigid and a flexible polymer, of two different rigid polymers, and a system of diblocks of and flexible pieces. The flexible components are modeled as chains freely rotating bonds, while the rigid components are modeled as of negligible thickness. The Landau-de Gennes expansion of the free is derived, and the form of the phase diagrams is examined. for the existence of generic diagrams is given in terms of Flory-Huggins and Maier-Saupe interaction parameters. The location the azeotrope in the rigid-rigid mixture is calculated analytically. nematic-isotropic phase transition in the rigid-flexible diblock (in n-block) copolymer system is also studied. In particular, the in the transition temperature with the number of monomers in a rigid block is determined.
