The first polymerization process involves opening the circular monomer and stitching many of them together, creating a long, open chain. Flexible and soft, the resulting material can be completely ...

Addition polymerization, also known as chain-growth ... chain are more stable than the double bonds of the monomer. While the process could continue indefinitely, most polymer/plastic manufactures ...

The simplified ethylene and propylene, finally, are the precious ingredients needed to make plastic's backbone. This next step unfolds through a process called polymerization, wherein those ...

There are hurdles still to overcome, but the new process is a big step towards a truly circular economy for plastic. Around 5 billion tonnes of plastic has gone to landfill since the 1950s ...

As an engineering plastic having high transparency and ... production thereof is mainly performed by means of interfacial polymerization reacting highly reactive phosgene with alcohol at the ...

"The chemistry that we're able to do with waste plastic definitely opens up a new path for recycling," said Conk. They've developed a catalytic process that can vaporize the two most common types ...

“Plastic foam is troublesome for most material ... When heated with ethanol and some zinc catalyst left over from the polymerization process, the vitrimer breaks down at its ester linkages.

"As a company focused on scalable materials for the circular economy, Novomer has committed significant resources towards its mission to cost-effectively address the plastic waste challenge ...
