EPOXIDATION AND DEGRADATION OF NATURAL RUBBER

摘要：

1. IntroductionEffective recycling of waste tires is important for environmental protection and resource utilization. Natural rubber (NR) is one of major components of tires. In order to achieve effective recycling of waste tires, it is necessary to investigate the utilization of its main rubber components. Epoxidation is a long-standing technique to improve the properties of rubbers. Hydrogen peroxide is one of effective stable catalysts with a broad scope for olefin epoxidations and alcohol oxidations because of its character of cheap, clean and give water as the sole byproduct. Catalysts based on tungsten in situ activation of H2O2 for the epoxidation of olefins are particularly attractive since tungsten is a readily available and inexpensive transition metal, with good catalytic stability and recycling efficiency without any specially designed organic ligands.
