Characterization of polystyrene networks by small‐angle neutron scattering

Abstract

Abstract Polystyrene networks prepared by anionic polymerization have been characterized by small‐angle neutron scattering. Two kinds of systems have been examined: (A) networks with labelled branch points allowing characterization of the spatial distribution of crosslinking points; (B) networks containing a low proportion of chains labelled with perdeuterated polystyrene in order to characterize the conformation of individual elastic chains of the polymeric network. The dependence of the results on swelling and uniaxial extension is discussed.
