Mixed up in the melee were pastel-colored marabou feathers—Galliano's homage to England's Queen Mother—18th-century hoopskirts and deliberately sleazy vinyl (just to add a contradictory jolt of modernity).

混合起来，在混战被粉彩色marabou羽毛-加里亚诺的祭奠英格兰的王母-十八世纪hoopskirts和故意sleazy乙烯基（只添加一个矛盾，动荡的现代性）。

It is to say that the patch of RAFT agent on the hairy chains.PS particles with the shell of copolymer of styrene and vinylbenzyl chloride were prepared by similar seeded and starved addition processes. RAFT agent with carboxyl end-group attached on the shell surface of PS particles by group reaction. Adding NIPA and photo-initiator into the continuous phase of polymerization system, hairy PNIPA were obtained.

最后，以表面负载一层乙烯基苄氯的亚微米级单分散聚苯乙烯微球为基质，将水溶性RAFT试剂与聚苯乙烯微球表面的官能团反应以负载到其表面，再在连续相中直接引入NIPA和光引发剂，RAFT聚合得到PNIPA毛发。

PVC is a vinyl letters, it is also a kind of polymer materials, PVC label paper common sub-white color, pearl white.

PVC是乙烯基的英文缩写，它也是一种高分子材料，PVC标签纸常见的颜色有亚白、珍珠白。

The possible mechanism was discussed. These bowl-shaped aggregates are promising candidates for nano reactor or drug carrier.4 2,7-dimethylene-1,4,6-trioxaspiro[4, 4]nonane with two vinyls was prepared to be used as electron-donor and crosslinker. The ATRP of this crosslinker and excess methylacrylate (used as electron-accpetor) was proved to mainly form homopolymers. With the chain-transfer agent S-1-Dodecyl-S\'-(α,α\'-dimethyl-α-acetic acid)trithiocarbonate, the copolymerization of the spiro hydrocarbon, maleic anhydride and MA by RAFT method produced star PMA.

这些由聚电解质复合物自组装形成的聚集体，在微反应器和药物释放等领域具有潜在的应用前景。4合成了双乙烯基的2，7-二亚甲基-1，4，6-三氧杂螺环烷，作为给电子单体和交联剂，与吸电子单体马来酸酐或过量的丙烯酸甲酯形成电荷转移络合物共同聚合，尝试了用ATRP和RAFT方法一步法合成星形聚合物。

Considering the low morphological stability of dye-doped polymer thin film and based on the above multi-chromophoric organic small molecules, six novel copolymers have been synthesized by the co-polymerization, in which there are three functions: 1, 8-naphthalimide as emitting moiety, oxadiazole as electron transporting moiety, and N-vinyl carbazole as hole transporting moiety.

考虑到有机小分子掺杂到聚合物膜中低的形态稳定性，我们在上面多发色团有机小分子研究的基础上，通过自由基引发共聚合成了六个新型的共聚物。在该类共聚物的侧链上含有三个功能团：1，8-萘酰亚胺单元、噁二唑单元和N-乙烯基咔唑单元。

Poly（p-vinylbenzyl succinimide） resin,which can be abbreviated to succinimide resin,was prepared by the reaction of chloromethylated polystyrene with succinimide in the presence of base. The succinimide resin was characterized by diffuse reflectance infrared Fourier transform spectrometry and elemental analysis.

摘 要：在碱性条件下，氯甲基化聚苯乙烯与丁二酰亚胺反应合成了聚（对乙烯基苄基丁二酰亚胺）树脂，采用元素分析、红外光谱对合成树脂的组成进行了表征。

Chlorine atoms were selectively introduced into the chlorin ring based on different reactivity between vinyl group at 3-position and 20-meso position by electrophilic addition and electrophilic substitution using hydrogen peroxide/hydrochloric acid, N-chlorosuccinimide, hydrogen chloride (or concentrated hydrochloric acid) as chlorinating reagent.

以过氧化氢/盐酸、N-氯代丁二酰亚胺、氯化氢为氯化剂，根据3-乙烯基和20-meso-位的不同化学反应活性，通过亲电加成和亲电取代反应，在二氢卟吩环上选择性地引进氯原子，完成8种未见报道的具有叶绿素-a基本碳架的氯代二氢卟吩衍生物的合成。

A base-catalyzed novel olefination methodology based on elimination of p-toluenesulfonamide:Treatment of diethyl cyanomethylphosphonate with catalytic amount of basegave the corresponding phosphoryl-stabilized carbanion, which added to the carbon-nitrogen double bond of N-tosyl imines.

新形成的氮负离子进一步攫取另一分子膦酸酯的活泼亚甲基氢形成加成产物同时再生出膦酰基稳定的碳负离子。加成产物消除对甲苯磺酰胺，高度立体选择性地得到-α-氰基-β-芳基-乙烯基膦酸二乙酯。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
