How Green Is Your Plastic?

Economical synthesis of polyacrylates and polymethacrylates from biobased materials

22-Jul-2021

Despite the best efforts of industry to work towards sustainability, most plastics (or polymers) are still made using non-renewable fossil fuels. However, researchers have now found an economical method for producing biobased acrylate resins. The study, published in the journal Angewandte Chemie, ...

Fabricating the future with a new environment friendly method of polymerization

Insights into a novel environment friendly method of polymerization involving non-metallic organocatalysts opens doors to efficient polymeric products

01-Mar-2021

Many materials in the modern world--from the plastics that dominate it to the electronic chips that drive it--are constructed of polymers. Given their ubiquity and the evolving requirements of our world, finding better and more efficient methods of making them is an ongoing research concern. In ...

Did Darwinian evolution begin before life itself?

How long-chain molecules are formed

24-Feb-2021

Before life emerged on Earth, many physicochemical processes on our planet were highly chaotic. A plethora of small compounds, and polymers of varying lengths, made up of subunits (such as the bases found in DNA and RNA), were present in every conceivable combination. Before life-like chemical ...

New route to chemically recyclable plastics

"This is about understanding really cool chemistry and trying to do something good with it"

27-Jan-2021

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers at Princeton's Department of Chemistry announces the discovery of a new polybutadiene molecule - from a material known for ...

Well oriented: Catalysts for isotactic polar polypropylenes

Japanese scientists developed a new approach that allows more suitable catalysts to be produced much more easily

03-Nov-2020

Polypropylene (PP) is one of the most widely used plastics in the world. By controlling the spatial orientation of the propylene building blocks and additional polar components, it should be possible to create a new generation of attractive, engineered, specialty plastics, with improved ...

New route to PHAs: naturally degradable bioplastics

Chemical catalysis for an existing class of biomaterials

25-Nov-2019

A tide of public momentum is swelling against the crisis of petroleum-based plastics, which are sitting in our landfills, floating in our oceans, and showing up in our air and even our food. Meanwhile, in a Colorado State University chemistry laboratory, polymer scientists are toiling toward what ...

Bottom-up Synthesis of Crystalline 2D Polymers

A Dream Finally Comes True

27-Sep-2019

Scientists at the Center for Advancing Electronics Dresden (cfaed) at TU Dresden have succeeded in synthesizing sheet-like 2D polymers by a bottom-up process for the first time. A novel synthetic reaction route was developed for this purpose. The 2D polymers consist of only a few single atomic ...
