        摘要：This article provides a review of enzymatic synthisis of sugar-containing polymers concluding sugar-containing linear polyesters,linear polymers with pendent saccharides which are called glycopolymers and others.Most of the sugar-containing linear polyesters can be synthesized with enzyme as the catalyst,while the glycopolymers must be synthesized by two steps:enzymatic synthesis of sugar-containing monomers and chemically polymerization of the monomers.

        摘要：Water based gels, comprising partially hydrolyzed polyacrylamide ( HPAM) cross-linked with chromium ( Ⅲ) , are now finding widespread use for near well-bore water and gas shut-off in the oil industry . The study on the mechanism and kinetics of the cross-linking reaction is very important to understand and improve the in-situ application of the gels technology .This paper reviewed several researchmethods on the mechanism and kinetics of the crosslinking reaction between HPAM and chromium ( Ⅲ) , such as Uv-visible spectroscopy, atomic force microspectrocopy ( AFM) , laser light scattering method, and focused on the rheological measurements.

        摘要：WLF equation is the special temperature dependence of motion of segment---the special motion unit in polymer.The change of energy is not important in the motion of segment.The most important,alternatively ,is the change of entropy.The reason is "giant" of macromolecule only,which causes a new parameter of structure---flexibility,its special temperature dependence of motion of segment---WLF equation and the special mechanical properties---rubber elasticity.
