Laser-Initiated Polymerization

这项研究的基本前提有两个：第一，充分利用激光引发聚合的能力，作为一种关键的新方法，探索各种不同类型单体体系在各种条件下的光聚合过程的动力学和机理；第二，建立确定激光引发聚合应用的操作参数的理论基础，例如成像、光纤涂层固化、微电路加工等应用。快速发展的激光引发聚合领域的重要性及其在美国工业中的使用潜力是不可小觑的。我们将继续研究简单的单官能团单体在本体和溶液中聚合动力学的基础，重点是多官能团/交联单体的激光引发聚合和液晶体系的聚合。此外，我们还建议研究其他聚合类型的激光引发反应，包括模板体系、阳离子引发聚合和微乳液，以努力为这些体系提供基本的动力学分析。

The basic premise for this research is two-fold: first, to exploit the full capabilities of laser-initiated polymerization as a critical and novel method for probing the kinetics and mechanisms of photopolymerization processes under a variety of conditions for a number of different types of monomer systems; and, second, to establish a rationale for defining the operating parameter for laser-initiated polymerization applications for such applications as imaging, curing of coatings for optical fibers, microcircuit processing, etc. The importance of the rapidly developing laser-initiated polymerization field and its potential for use in American industry cannot be minimized. We will continue to investigate the basics of polymerization kinetics of simple monofunctional monomers in bulk and solution, while placing special emphasis on laser-initiated of multifunctional/crosslinking monomers and polymerization of liquid-crystalline systems. In addition, we propose to investigate the laser-initiated of other polymerization types including templated systems, cationic-initiated polymerizations, and microemulsions in an effort to provide a fundamental kinetic analysis for these systems.
