中译英,
Emulsion polymerization is an industrially important process because of its potential to achieve high conversion,easy heater moval and environmental benefits.At the moment,a large number of polymer products are produced by emulsion polymerization.Due to these advantageous and market potentials,the design and the control of emulsion polymerization reactors have absorbed special attention in research.Different properties of the product can be considered when controlling the process:conversion,molecular weight distribution,particle size distribution(PSD),chemical composition,etc.The PSD is a key feature of the product which strongly influences viscosity and other attributes of the latex which are critical in applications.The modeling of emulsion polymerization process including the PSD is complex and still a challenging endeavor.The modelused in this work covers the main physical phenomena that influence the PSD in emulsion polymerization.

乳液相聚合在工业上是一个很重要的过程,因为它具有获得高转化率的潜力,简单的moval(我也不知是什么)和对环境的友好性.目前,一大类聚合物产品都是用乳液相聚合的方法生产的.因为有这些优点和市场潜力,乳液相聚合反应器的设计和控制在研究中受到了额外重视.产品的不同性质在控制过程中也需要被考虑:转化率,分子质量的分配,粒度大小的分布(PSD),化学成分,等等.PSD是产品的一项关键性质,因为它强烈的影响产品黏度和乳液的其他属性,这些性质在实际应用中都是十分关键的.考虑PSD的乳液相聚合过程设计是一项复杂而且仍然很有挑战性的工作.这一工作中使用的模型涵盖了在乳液相聚合过程中影响PSD的主要物理现象.
大概这样吧……moval是啥我再查查

Conclusions
The enzymatic oxidative polymerization of phenol in water
was achieved by the addition of the PEGMDE template.
The polyphenol was obtained in high yields as a precipitated
complex with PEGMDE.The presence of the
PEGMDE template in the aqueous medium greatly improved
the regioselectivity,yielding polyphenol with a
phenylene unit content near 90%.The FT-IR,DSC,and
XRD analyses confirmed the formation of a miscible complex
of polyphenol and PEGMDE by hydrogen-bonding
interaction.The present study also clearly shows that
mainly the carbon-carbon coupling between phenolic
radical intermediates takes place in the presence of
PEGMDE in water.Furthermore,the lack of organic solvents
in the present reaction system is environmentally
friendly.Investigations on the synthesis of new polymeric
materials by the enzymatic polymerization of phenol
derivatives using water-soluble polymers as templates are
under progress in our laboratory.

建议用coogle翻译功能,这个东西有点多,打字都要很久,你分给的也有点少,所以建议你加到50或者100分,或者用coogle翻译吧
