Research Initiation Award: Complex Polymer Fluids

摘要本研究的主要目的是了解聚甲基丁烯、聚乙烯和聚甲基丁烯-聚乙烯嵌段共聚物三元共混物的热力学性质和相行为。理论认为可能形成含有管状和片状分散相的复杂流体。时间分辨的小角中子散射和光散射测量将被用来确定微观结构以及相分离的演变。聚烯烃是石化工业中最重要的产品之一，用于制造许多塑料材料。由三元共混物组成的新知识和新材料可以改善现有聚烯烃产品的性能或扩展其新用途。

CTS-9308164 Polytechnic University Nitash P. Balsara ABSTRACT The principal objective of this research is to understand the thermodynamic properties and phase behavior of ternary blends of polymethylbutene, polyethylene, and polymethylbutene-polyethylene block copolymers. Theories suggest the possible formation of complex fluids containing tubular and lamellar dispersed phases. Time-resolved small-angle neutron scattering and light-scattering measurements will be employed to determine microstructure as well as the evolution of phase separation. Polyolefins are among the foremost products in the petrochemical industry and are used to make many plastic materials. New knowledge and new materials composed of ternary blends could improve the properties of current polyolefin products or extend their use for new applications.
