Experimental Study of High Pressure Copolymer Solution Behavior

摘要Mark A.McHugh Johns Hopkins University CTS-9500489生产特定市场应用的新型共聚物不仅取决于对共聚动力学的深入了解，还取决于对这些共聚物在工艺溶剂中的溶解行为的深入了解。代表潜在市场新产品的共聚物。虽然使用众所周知和现有的高压聚乙烯聚合技术生产这些共聚物在经济上是非常有利的，但要可靠和可重复地生产这些新产品仍然是一个相当大的挑战，因为关于这些共聚物在乙烯和乙烯-共溶剂混合物中的溶解度的现有信息很少。因此，这项拟议研究的主要重点是实验测定基于乙烯的共聚物-溶剂和共聚物-溶剂-助溶剂混合物的浊点或溶解度数据。

ABSTRACT Mark A. Mchugh Johns Hopkins University CTS-9500489 The production of new copolymers for specific market applications depends not only on an intimate knowledge of the kinetics of copolymerization, but also on a firm understanding of the solubility behavior of these copolymers in process solvents. The copolymers that represent potential new market products. While it would be highly advantageous economically to produce these copolymers using well-known, and existing, high-pressure polyethylene polymerization technology, there is a considerable challenge to producing these new products reliably and reproducibly since there is little available information on the solubility of these copolymers in ethylene and ethylene-cosolvent mixtures. Therefore, the major focus of this proposed study is the experimental determination of cloud-point, or solubility, data for ethylene-based copolymer-solvent and copolymer-solvent-cosolvent mixtures.
