Vlassopoulos et al. (1998) examined the gelation of three epoxy-rubber thermoset blends (based on TGDDM/DDS/(acrylonitrile/butadiene rubber/methacrylic acid copolymer) of the same chemistry but different pre-cure treatments. The pre-treatments used heat and catalysts to promote epoxy-carboxyl reactions, and there was some evidence of a decrease in gelation time and an effect on pre-gel rheology with these treatments. 

Basie introduction to rheology. This section provides a short description of the teehnology underlying a rheometer. Additionally, it includes some basic descriptions and characteristics of gel rheology. 

To demonstrate various aspects of gel rheology, a commercial fluorosilicone gel (Dow Corning DC4-8022) is used as an example. This platinum-catalyzed silicone gel is only lightly crosslinked and contains about half by weight of sol diluting the gel network.
