22 Feb 2023 --- Canadian researchers have developed a carotenoid-sourced compound to make a fully-degradable, soluble polymer that disintegrates with acid and sunlight. They note that the work lays the foundation for a new class of fully degradable conjugated polyazomethines that uses building blocks from nature. The research team combined 10-carbon dialdehyde and p-phenylenediamine to make three polyazomethines with different side chains.
