A new method of producing polyolefins made from hydrocarbons, Plastics are victims of their own success, so cheap, easy to use and multifunctional that the world is flooded with plastic waste.
Researchers have now announced a new method for producing polyolefins from hydrocarbons and the most common plastic building blocks, which are structured to overcome one of the biggest obstacles to plastic recycling.
This process will also enable the production of plastics from vegetable oils and other natural materials.
Polyolefins and their derivative products such as polyethylene and polypropylene are used for everything from shopping bags to industrial tubes.
For example, the properties of plastic hardness versus flexibility are partly determined by a chemical process known as branching: researchers say that high-branched polyolefins are used in products that require softness or flexibility, such as food bags, when using low branching. It produces hard plastic. A new method of producing polyolefins made from hydrocarbons.
According to Hart, different catalysts are traditionally needed to form different branching levels, which means that only one type of plastic can be produced at a time.
The new method allows branching to be modulated using a palladium catalyst with different amounts of aluminum chloride added.
which acts as Lewis acid; Aluminum chloride can be added at various points in the process in terms of abundance and inexpensive, where the resulting polyolefin has different branching properties.
This new process can solve two growing problems facing plastics manufacturers, how to dispose of plastic waste in an environmentally friendly way, and how to reduce the use of oil and natural gas instead of nutrients and other natural substances. A new method of producing polyolefins made from hydrocarbons.
Polymers currently used in, for example, everyday materials, food bags, milk kettles, toys, and medical equipment, do not easily mix when thawed for recycling chemicals.
This new polymer can sit on the border and facilitate the recycling of plastics with different properties. The process will work with different molecules to make polymers.
And, according to researchers, this platform can give up on producing a large number of functional plastics from natural oils and other molecular sources.
