环境降解塑料的降解原理及影响降解的因素（Degradation principle of environmental degradable plastics and the factors affecting degradation） Teacher Hu Hanjies article A variety of plastic products has been infiltrated into the various aspects of human society, it not only provides convenience for human life, become the necessities of human life, but also brought more serious environmental problems for human society. In order to solve the problem of white pollution caused by plastic products, all countries in the world are trying to find, research and develop new materials that can be degraded in the environment to replace the general plastic products which are polluting the environment at present. In the face of numerous degradable plastic varieties and various techniques in the development process, new varieties and new technologies of environmentally degradable plastics for us in the research of topic, when, how to identify what macromolecular compounds in the environment can be degraded in the environment, plastic is what is due to a degradation, research or industrial development can the necessary basic knowledge about the environmental degradation of new materials. Therefore, this article would like to discuss some personal opinions on this issue, based on the literature review, for the reference of interested people. First, the principle of environmental degradation of polymer materials The so-called environmental degradable materials (including environmental degradation, plastic) refers to polymer materials in use, can be small molecules in the environment of various factors automatically degrade into nontoxic. This process involves the disappearance of material (plastic) shape, the destruction of polymer condensed structure, and the degradation of polymer chains. The three processes are indispensable. In the three process, although the degradation of polymer chain is the most critical step, but the shape of the material is gone and condensed polymer damage to the structure of two
