Macromolecular condensed state involves crystallinestate and non-crystalline state of long-chainsynthetic and naturally occurring molecules. The noncrystallinestate may be a polymeric fluid, a rubberyelastic semi-solid or a rigid glass. In the early 1980sstudies were initiated in the CAS Institute of Chemistryon some basic issues in macromolecular condensedstate, which mainly include synthetic polymers, likeglass transition and effects of sub-T_g annealing, themolecular condensation process of long-chainmolecules, chain orientation in the amorphous state,liquid crystalline state etc. The studies were soon
