Modification of natural rubber latex. II. Natural rubber poly(methyl methacrylate) composite latexes synthesized using an amine‐activated hydroperoxide

摘要

AbstractComposite latex particles based on natural rubber latex have been synthesized to yield materials which may be formally regarded as interpenetrating polymer networks and semiinterpenetrating polymer networks. Methyl methacrylate was added to a carefully stabilized natural rubber latex and polymerizedin situusing an amine‐activated initiator,tert‐butyl hydroperoxide. The resulting materials were cast to yield solid sheets. The morphology of the materials was determined both by transmission electron microscopy and by dynamic mechanical analysis. In addition the stress–strain behavior was st
