Structure of Tough Multiple Network Elastomers by Small Angle Neutron Scattering

The chain conformation of model interpenetrated network elastomers was studied by small angle neutron scattering. Model double networks (DN) were made by first polymerizing and cross-linking partially deuterated ethyl acrylate in the presence of toluene, then by swelling these networks with either ethyl or methyl acrylate monomers subsequently polymerized. Model triple networks (TN) were made by repeating these swelling/polymerization steps one...
