No difference was found between the single chain elastic behaviors of isotactic and syndiotactic polystyrenes.

通过对具有不同立构规整性的聚苯乙烯的单链力学性质的研究，我们发现它们的弹性性质基本相同。

May send polystyrene to have the nature lightly, moderately-priced, the thermal conductivity to be low, the hygroscopicity is small, electric insulation performance good, sound-insulated, quakeproof, moisture-proof, formation craft simple and so on merits, thus widely serves as profession and so on construction, transportation heat preservation heat insulations, sound-insulated, the earthquake resistance material, to serve as the electric appliance, the measuring appliance, the glass products, the electronic products and so on cushion packing material and the food packing

可发性聚苯乙烯具有质轻、价廉、导热率低、吸水性小、电绝缘性能好、隔音、防震、防潮、成型工艺简单等优点，因而被广泛地用作建筑、交通运输等行业的保温绝热、隔音、抗震材料、用作电器、仪表、玻璃制品、电子产品等的缓冲包装材料和食品包装

He and his team grew tiny polystyrene spheres until they were some 200 nanometres across, before hardening them with a blast of heat.

他和他的团队，先培育聚苯乙烯球直到它们的直径为200纳米，再用一股强热将其硬化。

Though enantioslectivity in the epoxidation of some substrates with soluble polymer-supported tartrates is a little lower than that with solution-phase tartrates, it is higher than enantioslectivity with insoluble polystyrene resin-supported tartrates, linear poly s and corrosslinked poly s. It is obvious that soluble polymer-supported tartrates have good catalytic activity and enantioselectivity.

尽管可溶性聚合物支载的酒石酸酯在某些底物环氧化中的对映选择性比小分子酒石酸酯低一些，但明显优于文献报道的不溶性聚苯乙烯树脂支载的酒石酸酯、线形聚酒石酸酯和交联聚酒石酸酯配体，显示了良好的催化活性和对映选择性。

Two sheets of one-inch, pink, polystyrene foam was purchased at the local Home Depot store.

两张一英寸，粉红，聚苯乙烯泡沫塑料购买了在当地Home Depot的商店。

The humidity resistance and the sensitivity to chemical warfare agents simulants of the tuned films were also investigated.Self-assembled LBL polyaniline films were prepared from aniline monomers by in situ polymerization and the mechanism of film formation was discussed. It was proposed that the self-assembly of polyaniline occurred through the quick absorption of aniline monomer cations or aniline monomer cation radicals on the glass surfaces by electrostatic attractions to form homogeneous polymerization centers, then increased gradually by the way of upright to the glass supports for extensity, leading to the polyaniline chain growth. The polyaniline was doped under acidic condition to absorb anionic polyelectrolyte, such as sodium polystyrene sulfonate based on the electrostatic force, or to adsorb polymer based on hydrogen-bonding interactions, for example Polyvinyl Alcohol, and then recycled to fabricate_n or_n self-assembled multilayer films.

跟踪了原位聚合的具有纳米结构的聚苯胺多层自组装膜的成膜过程，提出了该自组装膜的成膜机理：聚合反应初始阶段的苯胺阳离子或苯胺阳离子自由基通过静电作用快速吸附到带负电荷的基片表面，形成均匀的聚合中心，然后以垂直于基片的方式进行链增长生成PANI；PANI在酸性条件下经现场掺杂后带正电荷，再通过静电作用吸附带负电荷的聚电解质如聚苯乙烯磺酸钠，或通过氢键作用吸附聚合物如聚乙烯醇，这样循环LBL-SA即得到_n或_n等原位聚合聚苯胺自组装膜。
