1.First, the current degradable plastics are all fatty chain polymers containing ester groups, and their mechanical properties are still far behind traditional plastics.
2.second, the cost of this type of ester group-containing polymers has no advantage compared with traditional plastics.
3. It is that the processing performance of this type of plastic has no advantage compared with traditional plastics, so it is difficult to promote and use. Traditional plastics have been industrialized since the 1950s, and the output and performance have been advancing at the same time before the 1970s. However, the molecular design did not consider the cycle of nature, which brought about the huge problem of white pollution. Therefore, after such a short period of development, it is very difficult to make degradable plastics compare to traditional plastics in all aspects.
