Describe the preparation of a polymer material that is almost inert with the atmospheric conditions and another polymer material that can disintegrate in the soil.
Answers
Answer:
The traditional polymer materials available today, especially the plastics, are the result of decades of evolution. Their production is extremely efficient in terms of utilization of raw materials and energy, as well as of waste release. The products present a series of excellent properties such as impermeability to water and microorganisms, high mechanical strength, low density and low cost due to manufacturing scale and process optimization . However, some of their most useful features, the chemical, physical and biological inertness, and durability resulted in their accumulation in the environment.
However, certain parts that are formed by small amounts of polymer (ie, a few grams) and may still be contaminated by food are difficult to be collected from nature, cleaned, sorted and recycled, both from the economic and also from the environmental pollution.
