Epoxies, crosslinked

The investigation of the gas permeation characteristics of epoxy-polyimide would also be interesting in noting the packing efficiency of the polyimide molecules and the effect of immobilization in an epoxy network would have on the permeation characteristics of various gases. The extent of epoxy crosslinking would also have an effect these properties of the composites. [Pg.133]

Photoinitiated epoxy crosslinking is generally based (with one exception on cationic ring-opening polymerization of the oxirane group, yielding polyether structures. [Pg.63]

The kinetics of the amine-epoxy crosslinking reaction have been studied in detail by a wide range of methods, and of particular importance is the correlation of the chemical changes, as the network develops, with the changing viscosity of the system. This has been facilitated by spectroscopic methods such as FT-NIR (Section 3.3.6), and the results of this analysis... [Pg.57]
