Cyclopropene monomers (shown here in ring-opened form with various substituents R 1 -R 4) can be precisely placed at various locations along a polymer. Each block in the polymer can consist of ...
Researchers from Shinshu University developed a two-step recycling process for depolymerizing the cyclic styrene-based vinyl polymers and recovering the monomers via single-step chemical ...
Several hindrances to the recycling of synthetic polymers, including material separation and post-treatment degradation of the macromolecular polymer chains, negatively affect the cost-efficiency and ...
Moving closer to this goal, Junpeng Wang and colleagues at the University of Akron developed a polymer that scientists can break down into monomers and then put back together to reuse (Nat. Chem ...
When the polymer powder and the monomer liquid are mixed, the monomers dissolve and diffuse to the surface of the PMMA. 30 In this study, the liquid monomer also dissolved the AAm monomer ...
All long, repeating chains are polymers, regardless of how many monomers are used. But when a polymer family includes copolymers, the term "homopolymer" is used to identify the single monomer type.
Polymer enables tougher recyclable thermoplastics Date: August 16, 2021 Source: Cornell University Summary: Researchers took a middling monomer and, by using a special catalyst, they created a ...
DOI: 10.1080/27660400.2024.2425178 Polymers, such as plastics, are essential in many aspects of life and industry, from packaging and cars to medical devices and optic fibers.
A controlled/“living” click polymerization method developed by researchers at Institute of Science Tokyo and Nagoya University enables precise chain-growth of AB-type monomers—traditionally limited to ...
