What are functional polynorbornenes?
Functional polynorbornenes are polymers that contain reactive functional groups, making them suitable for various applications.
Why is the glass transition temperature important?
The glass transition temperature indicates the temperature range where a polymer transitions from a hard and brittle state to a rubbery state, affecting its performance in applications.
What is catalytic insertion polymerization?
Catalytic insertion polymerization is a method that allows for the formation of polymers through the insertion of monomers into a growing polymer chain, facilitated by a catalyst.
How does this method simplify polymer synthesis?
This method eliminates the need for special purification steps, making it more accessible for researchers new to polymer synthesis.
