        摘要：This paper reviews the application of relaxation of solid state NMR in the study of polymer. It discusses the relaxation process of magnetic nucleus and its relation with molecular structure and molecular motion in following five aspects: (1) the spin-lattice relaxation process, (2)The 13 C spin-lattice relaxation process in the rotating frame, (3)The rate of cross polarization and the 1H spin-lattice relaxation process in the rotating frame, (4)The spin-spin relaxation process, (5) The relation of line shape and molecular motion.

        摘要：The paper is concerned with the possibility and realizing approaches of living radical polymerization. It is required that growing radicals are in a dynamic equilibrium with the dormant species and a low stationary concentration. In these system the polymerizations have some nature of living polymerization, such as the linear increase of molecular weight with time and conversion and the formation of polymers with narrow molecular weight distribution and block copolymer.

        摘要：In this paper,recent attempts to study the morphological characters of one-dimensionally oriented poly (ethylene terephthalate)〔PET〕have been covered. In particular,several articles for analyzing the non-crystalline structure and examining the mechanical deformation mechanism have been reviewed. Emphasis was also placed on the new techniques for preparing high performance PET fibers and mechanical properties of the resulting materials.
