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 ...

The most common method for synthesizing polymers with a carbon–carbon main chain backbone is vinyl polymerization, by which ...

If the monomers contained just the cyclooctene, the energy due to ring strain would be high enough that the polymer wouldn’t recyclize into monomers, making the reaction irreversible.

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 ...

Monomer Polymer, a US company that specialises in manufacturing speciality monomers and sophisticated polymers, has agreed to market the technology worldwide. Discovered by the CSIRO in 1998, RAFT is ...

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 ...

Hyperbranched polymers have desirable properties as novel materials, and may be synthesized from homopolymerization of multi-vinyl momomers, although this can form insoluble products at low ...

Accessing synthetic two-dimensional polymers that are analogous to graphene is synthetically and analytically challenging. Now, single crystals of a simple-to-make monomer have been grown and then ...

For more than two decades, the Ihara research group has been focusing on the development of new methods for polymer syntheses using diazocarbonyl compounds as monomers. They found that ...

Study: MXene-assisted polymer coating from aqueous monomer solution towards dendrite-free zinc anodes. Image Credit: nevodka/Shutterstock.com How do Coatings Improve Functionality? The protective ...

Key opportunities in the Vinyl Chloride Monomer (VCM) market include growing demand in construction and automotive industries, driven by urbanization and infrastructure development. Technological ...

Chemical recycling is a newer method that breaks the polymer chains back down into their monomer units and then strings the units back together. The recycled plastic is as good as new.
