Local Structure of Network Resins
Abstract
The objective of the project is to understand the local molecular organization in epoxy resin systems, and thus to establish a bridgehead in relating chemical composition to final properties. The approach has been two-pronged. The local molecular structure of the cross-linked system has been modelled using advanced computer simulation systems which provide a prediction based on available chemical knowledge. A parallel experimental programme has been established in which wide angle X-Ray diffraction is measured from both oriented and unoriented samples. The experimental data are compared with diffraction patterns calculated from the computer generated molecular model. The conformational flexibility has been calculated for a range of differently substituted varients of bis-phenyl A, and these units incorporated into simple models of the molecular network.
