        摘要：Biospecific functional polymers are tailored by randamly substituting a polymeric backbone with functional groups or chemical residues which mimic the constituents of the biopolymer active site. This article reviews two kinds of biospecific functional polymers: heparin like functional polymers and adhesive protein like functional polymers.

        摘要：The monodisperse polymer microspheres with large size are a kind of macromolecular particles which have been developed in recent 20 years. They are of wide prospects for using in many fields such as standard measurement, information, medicine, immunity, biochemistry etc. The syntheses and applications have become an active topic in polymer science. In the present paper,the situations of syntheses,applications and theoretical study both in home and in abroad for monodisperse polymer microspheres with large size are reviewed. It focuses on two kinds of efficient techniques,i. e., dispersion polymerization and seed swollen,for preparing polymer microspheres. Besides, the applications of monodisperse polymer microspheres with different particle morphologies and surface characteristics in various fields are introduced.

        摘要：Conjugated polymers whose main chains are composed of unsaturated π - bonds have band gaps which spans the all - important visible region of the spectrum. Therefore, there are a variety of possible application to electronic devices,such as light emitting diodes. In this paper, a review is given on the basic working principles and construction and developmental prospect of electroluminescent polymer devices.

        摘要：Proton Magnetic Resonance Thermal Analysis (PMRTA) has been proven to be a convenient yet powerful technique for the thermal analyses of organic and polymeric materials. This technique essentially records the proton magnetic resonance (1H NMR) spin - spin relaxation signal of a sample at various temperatures,which decays rapidly for rigidly bound molecules,but more slowly as molecular mobility is acquired. PMRTA monitors physical and chemical changes of a sample,e. g. glass transition,melting and crystallization,softening and hardening as well as thermal degradation and polymerization etc. by automatically detecting the relaxation signals in a programmed heating and cooling process. PMRTA was first initiated by Lynch and Webster et al. in the early 1980s,and commercial instrument has become available now. This article shows some examples to highlight the functions and capacities of this unique technique. In addition,the principles of PMRTA and instrumentation are briefly reviewed.
