英语翻译
Having briefly examined the structure of organic packings and the various routes
in their manufacture,the most important features may be summarized as follows:
> Hydrophilic as well as lipophilic organic packings are synthesized with a controlled
pore and surface structure depending on the type of monomer/comonomer
and the polymerization reaction.Surface structure can be altered by
controlled consecutive surface reactions.
> In accordance with the bulk composition,polymer packings are stable across
almost the entire pH range,particularly under strong alkaline conditions.
> Chemical stability is affected by oxidizing and reducing solutions.
> Although cross-linking reactions have been optimised in as much as rigid pressure
stable particles can be manufactured,some remaining swelling property is
often noted when changing the solvent composition in HPLC.
> As in the manufacture of silica,porosity,pore size,and surface area of polymer
packings can be adjusted over a wide range,and micro-,meso-,and macro- as well
as non-porous beads are synthesized reproducibly.
3.2.4.2 Hydrophobic Polymer Stationary Phases
The synthesis of cross-linked copolymers of styrene and divinylbenzene has been
studied intensively and is well documented.The starting monomer is styrene,and
divinylbenzene (DVB) is used as cross-linker.The amount of DVB can reach up to
55wt.%.At 55% DVB,the copolymer shows practically no swelling and possesses a
permanent porosity.Figure 3.21 illustrates the network structure of poly(styrenedivinylbenzene)
(St-DVB).
Commercial products differ in bead size and pore size.There are even non-porous
products on the market,designed for the rapid separation of peptides and proteins
by reversed phase HPLC (Maa and Horvath,1988).St-DVB copolymers are stable in
the pH range 0–14.They find increasing application in the separation of low molecular
weight compounds,peptides,and proteins by means of reversed phase chromatography
(Tanaka et al.,1987,Tweeten and Tweeten,1986) and as parent materials
for the synthesis of derivatized packings in interaction chromatography of biopoly-mers (Unger et al.,1987,Regnier,1987).Numerous other organophilic polymer
packings have been synthesized for size exclusion and interactive HPLC after suitable
derivatization.They are reviewed in depth by Mikes (1988).

简略的查看有机包装物的结构和他们各种各样的生产途径,最重要的特点可以总结如下：
》亲水性和亲脂性有机包装都是经过一种可控的小孔和表面结构合成的,这种结构取决于单体|单聚体以及聚合反应的类型.表面的结构可以通过连续的表面反应来改变.
》与原始组成一致,多聚体包装在整个PH范围内都稳定,特别是强碱性环境.
》化学稳定性受到氧化性和还原性溶液的影响.
》尽管交联耦合反应已经在尽可能多的严格压力下被优化,稳定的粒子可以制备出来,当高效液相色谱法中的溶剂成分改变的时候,一些膨胀性质经常会注意到.
》像硅胶的制作过程一样,多聚体包装的多孔性,孔径大小和表面积可以在宽范围内调节,微的,内消旋的,巨大的和无孔的玻璃粉可以可再生的合成.

早上好,我继续翻译下面的
3.2.4.2.疏水的多聚体固定相
苯乙烯和二乙烯基苯的交联耦合共聚体的合成已经被深入研究和很好的证实了.起始的单聚体是苯乙烯,二乙烯基苯作为耦合交联剂.二乙烯基苯的量可以达到55wt.%(WT是什么意思我也不懂）在二乙烯基苯是55%时,共聚体几乎没有肿胀并且具有恒定的多孔性.图3、21阐明了苯乙烯二乙烯基苯共聚体的框架结构.
商业产品在玻璃粉的尺寸和孔径大小方面有差异.在市场上甚至有无孔的产品,它是为在反相高效液相色谱法中快速分离蛋白质和肽类而设计的.(Maa and Horvath这两个人在, 1988年).苯乙烯和二乙烯基苯聚合物在PH0-14稳定.他们发现了依靠反相色谱分离小分子化合物,肽类和蛋白质这种应用的增加(Tanaka等 人于1987和Tweeten and Tweeten二人与1986) 和在生物多聚体的交互色谱中合成衍生物包装材料的过程中作为母体的增加.(Unger等人于1987, Regnier于1987).大量的其他亲有机物质的聚合物包装材料在合适的衍生反应下通过空间排阻色谱和交互色谱被合成.他们被在1988年被Mikes 深入研究.
