This Inter-American Materials Collaboration involving New Jersey Institute of Technology (NJIT) and Universidad Nacional Autónoma de México (UNAM) will develop new backbone chemistries for very high performance fibers, films and plastics incorporating renewable resource monomers derived from common agricultural crops. It is expected that these materials will have the density of common plastics yet exhibit the strength and stiffness usually associated with metals. The basic building block of the proposed research is isosorbide, a glucose derived chemical (glucose is a common product of either starch or cellulose fermentation) which can be incorporated into the backbone of polyesters and other common polymers. These materials are expected to be renewable, load bearing, lightweight, environmentally friendly and energy efficient. This project explores the science behind achieving very high mechanical and thermal performance in polymeric materials. The relationship between ordered polymer liquids (liquid crystal polymers) and high performance polymeric products is well established. This project will lead to new understanding of the relationship between polymer backbone chemistry, liquid crystal phase creation and liquid crystalline polymer performance. Specifically: this project focuses on: The identification of new, controlled stereochemistry mesogenic and disrupting monomers from renewable resources Increased definition of how backbone chemistry defines LC phase structure, chain interactions and entanglements, rheology and solid state mechanical properties Amplification of how processing and annealing interacts with backbone chemistry to define LCP performanceThe program builds a strong and sustainable program between UNAM and NJIT, providing a forum for scientific cooperation between the US and Mexico over a broad range of physical science and engineering area. This research provides an avenue for exchange of personnel ranging from senior faculty to high school students

这项涉及新泽西技术学院（NJIT）和Nacional NacionalAutónomaDeMexico（UNAM）的美洲材料合作将开发出新的骨干化学，以构成非常高性能的纤维，电影和塑料，并结合源自常见农业农业的可再生资源。预计这些材料将具有常见塑料的密度，但会暴露出通常与金属相关的强度和刚度。拟议的研究的基本基础是异森质，这是一种葡萄糖衍生的化学物质（葡萄糖是淀粉或纤维素发酵的常见产物），可以将其掺入多酯和其他常见聚合物的骨架中。预计这些材料将是可续签，负载轴承，轻巧，环保和节能的。该项目探讨了在聚合材料中实现非常高的机械性和热性能的科学。有序聚合物液体（液晶聚合物）与高性能聚合物产物之间的关系已经很好地确定。该项目将导致对聚合物主链化学，液晶相创造和液晶聚合物性能之间的关系的新理解。具体：该项目的重点是：识别新的，受控的立体化学中源和破坏来自可再生资源的单体，可以增加对主链化学如何定义LC相结构，链相互作用和纠缠，流变学和固态机械性能与处理方式相互作用的稳固化学和固定构建的定义和固体机械性能的定义，以确定性和固定构建良好的化学和固定的构建，以确定型和固定的构建，以确定back骨的构建和固定型。 NJIT，在广泛的物理科学和工程领域提供了一个美国与墨西哥之间科学合作的论坛。这项研究为交换人员提供途径，从高级教职员工到高中生
