Germany's Bayer AG said on Thursday it has kicked off a massive China expansion plan with a joint venture deal with Chlor Alkali to build a $450 million polycarbonate plant in Shanghai.

德国化工巨人拜耳药业集团周四表示，该公司已与上海氯碱化工有限公司签订合作合同，在上海建立一个总资产达4.5亿美元的聚碳酸酯工厂，这也是拜耳在中国进行大规模投资计划的第一步。

The invention uses the method of the fusion and direct polymerization to prepare the carboxyl-terminated lactic acid prepolymer and then copolymerize with the aliphatic polycarbonate; then the reaction is done in the twin-screw extruder to screw out the extension chain and the good polylactic acid copolymer is made.

本发明采用熔融直接缩聚的方法制备出羧基封端的乳酸预聚物，接着再与脂肪族聚碳酸酯二元醇进行共聚，然后再在双螺杆挤出机中进行反应挤出扩链，制备性能良好的聚乳酸共聚物。

The effects of the variety and content of the antioxidants and that of environment conditions on the thermostability and degradative kinetics of PC were also investigated.

通过在聚碳酸酯中加入不同抗氧剂以提高其热稳定性，研究了抗氧剂的种类、用量、环境条件对PC热稳定性能和降解动力学的影响。

The synthesized PCU was then characterized by infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, small-angle X-ray scattering, and tensile strength measurement. The IR showed that the polymer synthesized by the above two methods both have the polycarbonate-urethane structure and the tensile measurement showed good mechanical performance of the polymer. The DSC and TGA data showed that there is an obvious soft-hard glass transition area, which indicated the existence of the micro-phase separation structure. The extent of the phase separation was affected by the ratio of starting materials, the molecular weight of PCD, and the polymerization method. The decomposition upon heating was observed in two steps. SAXS result showed that the radius (r_2), the distance between domains (d_2), and gyral radius (R_2) of hard segment micro-domain were fairly affected by the starting materials ratio and soft segment content.

IR结果表明两种方法合成的聚合产物均具有聚碳酸酯聚氨酯的结构；拉伸实验表明聚合产物具有良好的力学性能；DSC、TG结果表明，聚合物呈现出较为明显的软硬段玻璃化转变区，表明存在微相分离的结构，相分离的程度受原料配比、软段分子量、聚合方法的影响，其热分解分为明显的两个阶段； SAXS结果表明，聚合物原料配比、软段含量的变化对硬段微区回旋半径R_2，微区间距d_2，微区半径r_2影响不大其值分别为9.5(A|°、29、7.4，但对软段的微区半径及间距影响较大，随着软段含量的增大，软段微区的半径r1和间距d1都增大。

An advanced non-destructive measurement technique was applied for the first time in the research of two-phase transport of gas-water in coal seam. The home-made triaxial osmoscope which is made up of non-magnetic polycarbonate material and can change confining pressure, axial pressure and pore pressure, was placed into the magnetic cavity of NMRI instrument.

首次将先进的无损检测NMRI成像技术引入煤层中气水两相运移的研究领域，将自主设计研制的、可同时改变围压、轴压和孔隙压的、非磁性聚碳酸酯材料制成的三轴渗透仪置于NMRI成像仪磁体腔中，通过气驱水和水驱气NMRI试验实时观测了气水流动规律。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
