Viscoelastic properties of carboxyl-terminated (butadiene-co-acrylonitrile)-based composite rocket propellant containing tris (2,3-epoxypropyl) isocyanurate as bonding agent
The influence of tris (2,3-epoxypropyl) isocyanurate as a bonding agent on the polymer network characteristics as well as rheological properties of [carboxyl-terminated (butadiene-co-acrylonitrile)/polyglycidyl ether of glycerol and epichlorhydrin] - based composite propellant was investigated.
