Abstract

Liquid size exclusion, adsorption, and bonded‐phase high performance liquid chromatographic (HPLC) methods have been developed to monitor the chemical compositions of epoxy resin prepregs. Examples are given to illustrate how multiple detectors and oligomer analysis techniques may be used to identify prepreg components and to discriminate between epoxy resins obtained from different manufacturers. The results of a case study in which HPLC methods were used to monitor compositional variations in batches of a commercial prepreg over a four year period are discussed. Finally, examples demonstrate how HPLC may be applied to monitor prepreg aging and to measure the extent of prepreg staging.

The application of liquid chromatography coupled to mass spectrometry (LC-MS) for the analysis of epoxy resins is shown in two examples. Electro spray (ESI) and atmospheric pressure chemical ionization (APCI) are compared with respect to the ionization of diglycidylether of bisphenol A-based (DGEBA)

Carboxyl-terminated poly(2-ethylhexyl acrylate) (CTPEHA) liquid rubbers of different molecular weights and functionalities (LR-1 to LR-6) were synthesized by bulk and solution polymerization techniques. The liquid rubbers were characterized by nonaqueous titration, vapor pressure osmometry, and gel
