聚苯乙烯

This article reports a new kind of copolymer, non polar polar terpolymer : poly(styrene-butadiene-methyl methacrylate ) P(S-b-B-b-MMA prepared by anionic polymerization with n BuLi as initiator, 1,1 diphenylethylene as capping agent and lithium 2-(-methoxyethoxy) ethoxide as complex agent.

以正丁基锂为引发剂， 1 ，1-二苯基乙烯为戴帽剂， 2-(2-甲氧基乙氧基)乙氧基锂为络合剂，在环己烷、四氢呋喃混合溶剂中，采用阴离子聚合法，于－70℃～－40℃合成了非极性-极性的三嵌段共聚物聚苯乙烯-聚丁二烯-聚甲基丙烯酸甲酯，并借用GPC、1H-NMR、DSC、TEM、IR等仪器对共聚物进行了表征。

Not long thereafter, in the same period, the exilic Ps.

不久，在同一时期，放逐聚苯乙烯。

Electrophoresis measurements of uniform colloid particles including latex and haematite particles have been made in various chemical conditions to test the developed model.

在不同化学条件下，对均匀胶体颗粒(包括聚苯乙烯Latex颗粒和α-Fe_2O_3颗粒)进行电泳测定来验证该模型。

In addition, it is also demonstrated that the haloid ions co-absorbed on the assembly play an important role in controlling the charge transfer between PATP and silver substrate.

4利用聚乙烯吡咯烷酮共聚对聚苯乙烯微球的表面改性进行碘催化剂的固定化，制备粒径均一、可循环使用的催化剂微粒。

This planet is only as dense as expanded polystyrene, 70 times less dense than the planet we're standing on, said professor Coel Hellier of Keele University.

来自Keele大学 Coel Hellier教授说：&这颗行星仅仅和聚苯乙烯的密度一样大，比我们所站立的这颗行星密度低70倍&

The silica/Polystyrene monocore-shell nanocomposite particles(95nm in diameter) were synthesized through miniemulsion polymerization by using sodium dodecyl sulfate surfactant,hexadecane costabilizer in the presence of silica particles(50nm in diameter) coated with methacryloxytrimethoxysilane.

采用细乳液聚合法，以3-甲基丙烯酰氧基丙基三甲氧基硅烷(KH570)表面改性的直径50nm的氧化硅粒子为核，在乳化剂、助乳化剂、引发剂存在的情况下制备了小粒径、单核核壳结构氧化硅/聚苯乙烯纳米复合微球。

Due to great amount of double bond on rubber chain,a lot of intramolecular reaction occurred in the system,which made the uncontrolled cross-linked system into a controlled cross-linked copolymerization,resulting in chain growth can't go illimitably in cross-linking process.

苯乙烯和二乙烯苯共聚体系是典型的不可控制的交联聚合体系，加入天然橡胶后，通过阳离子聚合方法，生成三元共聚物线团，由于橡胶分子链上含有大量的双键，聚合体系中能进行分子内反应，使不可控的交联聚合体系成为可控的交联聚合体系，其链增长不能无限制进行，从而可以合成可溶解的交联的聚苯乙烯-二乙烯苯-天然橡胶聚合物。

PS Jerm - forgetable is spelled with two T's, but I don't think spelling and grammar are the points of the post.

聚苯乙烯Jerm -f orgetable拼写有两个T的，但我不认为拼写和语法的点后。

The research result also showed that aminoalkylferrocene and new ferric alkyldithiocarbamate were effective initiators of the two kinds of biodegradation of the PE film; and new nickelous alkyldithiocarbamate could effectively control the initial process of its biodegradation; and PE film with them had better environmental degradability.

其中聚 酯、聚酰胺和聚氨酯等聚合物是通过H'或 OH_催化的水解降解引发过程，而聚乙烯、聚丙烯和聚苯乙烯等聚烯烃主要是通过光、热、氧和过渡金属离子催化的光一氧降解引发过程。但它们的最终可被生物吸收的产物都是低分子量的羧酸。

It was found that the transition from coil to helix was completed in the concentrated solution ofiPS/octadecyl benzoate system which has never been reported before.

在一般的短链分子溶剂中，只有在温度降至很低，等规聚苯乙烯的分子链才有可能部分规整排列。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
