Different Spatial Heterogeneity of Networks Prepared by a Two Stage Irradiation of Natural Rubber
Natural rubber networks were prepared by a two stage gamma-irradiation of rubber latex to yield materials of different spatial heterogeneity. The maximum overall dose is 250 kGy for each sample. Characterization of sample include swellling, ESR measurements using spin probe and mechanical measurements. The application od spin probe method enables to estimate network morphology from the complex ESR spectra. The morphology of the network is determined by the dose ratio of preirradiated and nonirradiated latex at the same overall dose. The potential effects of spatial heterogeneity on mechanical properties of rubber network are discussed.
