U.S.-China Cooperative Research: Polymerization and Processing of Ultra-high Molecular Weight Poly(ethylene terephthalate)

这个美国与中国合作的研究项目的目的是开发合成并加工聚对苯二甲酸乙二醇酯纤维的技术，使其具有超高强度和高熔融温度。该材料的制备将分两步进行：首先，采用固相聚合法制备超高相对分子质量的线型聚合物，然后进行溶液/凝胶纺丝，对长链分子进行取向。国际合作将使拥有不同和互补的专业知识和设备的首席研究员(PI)受益：美国的PI Hsieh拥有纤维分析和聚合物表征的仪器，而中国的PI拥有纤维纺丝的专业知识和设施。

The purpose of this US-China collaborative research project is to develop techniques to synthesize and then process poly(ethylene terephthalate) (PET) fibers so that they have ultra high strength as well as a high melting temperature. The material will be made in two steps: first, solid state polymerization will be used to produce the ultra-high molecular weight linear polymer, followed by solution/gel spinning to orient the long chain molecules. The international collaboration will benefit both principal investigators (PI) who have different and complementary expertise and equipment: the American PI Hsieh has the instrumentation for fiber analysis and polymer characterization, while the Chinese PI has the expertise and facility for fiber spinning.
