In semicrystalline polymers like polyethylene (PE), rigid crystalline regions in which chains are periodically stacked act as physical crosslinks between rubbery amorphous regions. Both PS and PE ...

Like polypropylene, P3HB has methyl groups poking off its polymer backbone. The form of P3HB that’s made by bacteria has all its methyl groups aligned in the same direction. This results in a strong, ...

In a paper published in Polymer Science & Technology, an international team of scientists explores an effective protocol for toughening vitrimers based on dioxaborolane metathesis through introducing ...
