        摘要：This paper presents a review on a lot of asidolysis polymers in the 1980' s. A detailed classification of the polymers are given. The characteristics of their structures are illustrated from the view point of chemistry and on these grounds their acidolysis mechanism are explained. The prospects of using them for the imaging materials, especially chemical amplification resists, are also forecasted.

        摘要：The criteria for cellulose and its derivatives to form a liquid crystalline (LC) phase are discussed. Both lyotropic and thermotropic LC properties are reviewed. The rheological properties, formation and processing of LC cellulose and its derivatives are introduced. Fibrillar and banded structure are observed for the fibres and films which have medium mechanical properties. The understanding of cholesteric-nematic phase transition has not been completely explained. Future research activity on LC eellulose and its derivatives is mentioned in this article.

        摘要：In this paper, according to the surface properties of latex particles, the effects of influence the stability behaviour of polymer latexes are summariesed as: electrostatic effect, steric effect, attractive effect, solvation effect and interface effect. Then the basic principles of steric stability are introduced, in which, the methods to estimate the steric interaction potential Vs are discussed emphatically.

        摘要：The principles, properties and production of synchrotron radiation have been briefly described. A general review on the application of this technique in polymer research such as in the field of crystallization in oriented state, melting of crystallized polymer, phase separation of polymer blend, crystal modification transitions and the formation of crazing has been made.
