摘要：

One alternative to enhance the degradability of polyethylene is the addition of prooxidant substances to their matix. The polymer materials are called oxo-biodegradable. Current investigation aimed to assess the abiotic degradation of linear, low densit polyethylene (LLDPE), formulated with soya powder and cobalt stearate as prooxidant additives. The blends of LLDPE/soya powder are to improve the degradability of the materials. The samples with different blends ratio and fixed amount of cobalt stearate was buried into natural soil. It was found that the tensile strength and elongation at break of the eroded materials from the pro-oxidant activated samples were significantly lower than the control sample without cobalt stearate. These samples underwent biodegradation and gave weight loss values uti to 9% over 6 months' of soil burial. The blends with higher soya powder content shows higher degradation in compost medium.
