Abstrakt: A novel technique for the analysis of the molecular weight distribution functions of crosslinked polymer chains is proposed. The technique is based on the relation between the high-temperature nuclear magnetic resonance free induction decay and the network structure. The method is used to study thermally and mechanically activated degradation of polyesterurethane networks. [ABSTRACT FROM AUTHOR]
