A)
Polypropylene (PP)
B)
Polyvinyl Chloride (PVC)
C)
Polydiketoenamine(PDK)
D)
Polyethylene Terephthalate(PETE)

Correct Answer : Option (C) - Polydiketoenamine(PDK)

Note : U.S. Department of Energy's Lawrence Berkeley National Lab in California created a new 100% recyclable plastic named Polydiketoenamine(PDK). This can be broken down and used without the loss of quality. It can be formed into a different shape and colour. Plastics are made of polymers, chains of hydrogen and carbons.The leader of this study is Peter Christensen. The research is published in the journal Nature Chemistry.The researchers discovered that the new PDK material has wide range of thermal and mechanical properties. It can be used in textiles, foams and 3D printed materials.
