        摘要：The macromolecular chain in single-chain condensed state is of looped chain conformation because of van der Waals attractive interaction between the intra-chain monomer units along the chain. As the attractive interaction between intra-chain monomer units in multi-chain condensed state is shielded by the attractive interaction between inter-chain monomer units of the neighboring chains in inter-penetration, the molecular chain in multi-chain condensed state is of Gauss conformation. The methods of preparing samples of single-chain condensed state, the experimental observations of single-chain single crystals, single-chain glasses and the stretching of solvent swollen single-chain rubbery state are briefly discussed. The process of transition from a single-chain condensed state to a multi-chain condensed state, that is the process of polymer coil inter-penetration, is a problem lacking basic understanding at the present time.

        摘要：Owing to the high performance properties and special functional properties, polymer/ clay nanocomposites become of greater general interest. From experiments it has evidenced that organoclays are easily intercalated by epoxy resins, and exfoliated during the curing process to form nanocomposites. In this paper, the research achievement of formation mechanism, mechanical properties and morphology as well as the applications of epoxy/nanocomeposites were reviewed.

        摘要：In this review, the space-grade RTV silicone materials and their outgassing property of heat vacuum are presented. Spare-grade silicone materials were exposed to a vacuum of 1.33 ×10-4 Pa and a temperature of about 125℃ for 24 hours. Total weight loss of the material is less than 1% . The product is treated by liquid-liquid extraction or thermal vacuum to reduce weight loss and vapor condensation under vacuum.

        摘要：There are two kinds of judgement to goodness of the solvent in polymer solutions. One is χ=1/2, from the free energy of Flory-Huggins mean-field calculation and the second Virial coefficient in the expansion of the osmotic pressure for dilution solution; another is χ=0, from the mixing heat. The former occurs in the current textbooks about polymer physics in China, but the author prefers the latter and gives his reasons.
