The project deals with a fundamental study of crosslinking polymers at gel point, i.e. at the transition from liquid to solid state. A simple physical relationship has been developed which involves a single material parameter, strength, which is able to describe limited visco-elastic phenomena at visco-elastic transition (VET). This research aims to establish the validity over the entire frequency range. Experimental work would involve the use of a range of polymeric materials and physical characterization techniques.

该项目涉及凝胶点交联聚合物的基础研究，即从液态到固态的转变。建立了一个简单的物理关系，该关系涉及单一的材料参数，强度，它能够描述粘弹性转变（VET）时的有限粘弹性现象。本研究旨在建立在整个频率范围内的有效性。实验工作将涉及使用一系列聚合物材料和物理表征技术。
