What is the role of triethylborane (TEB) in the synthesis of graft copolymers of cod collagen?

Label:chem

Topic
A study focuses on the synthesis of graft copolymers using cod collagen as the base material. Triethylborane (TEB) is used as a polymerization initiator in the presence of butyl acrylate (BA) and vinyl butyl ether (VBE).
Answer
Triethylborane (TEB) acts as a radical initiator in the synthesis of graft copolymers. It forms radicals during its oxidation by oxygen residues, which then react with collagen, leading to the grafting of synthetic monomers (BA and VBE) onto the collagen macromolecules. This process helps in forming three-dimensional, branched, and crosslinked structures suitable for regenerative medicine.
