Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids. Webb7 apr. 2024 · More appealingly, PEOx exhibited a green closed-loop recycling characteristic by thermolysis to a cyclic monomer and repolymerization to the polymer. Accordingly, the successful scale-up preparation of the high-performance PEOx material shows a potential commercial opportunity toward marine degradable plastics.
WebbOne of these fractions, naphtha, is the crucial compound for the production of plastics. Two main processes are used to produce plastics – polymerisation and polycondensation – and they both require specific catalysts. In a polymerisation reactor, monomers such as ethylene and propylene are linked together to form long polymer chains.
