Degradable polymer palstic have been widely used in various fields. However, the used plastic waste has caused environmental and social hazards. Some developed countries have successively formulated regulations to restrict or prohibit the use of non degradable plastics in some occasions and require the use of degradable plastics. Therefore, governments and the plastic industry all over the world attach great importance to the research and development of degradable plastics while formulating effective measures for the treatment and recycling of waste plastics. With the coordination and support of the governments, degradable plastics have become a research hotspot in the international plastic industry.
