How does the presence of triethylborane (TEB) affect the structure of the resulting graft copolymer?

Label:chem

Topic
Triethylborane (TEB) is used as an initiator in the graft copolymerization process involving cod collagen, butyl acrylate (BA), and vinyl butyl ether (VBE).
Answer
The presence of triethylborane (TEB) affects the structure of the resulting graft copolymer by facilitating the formation of radicals that initiate the grafting process. This leads to the formation of a copolymer with alternating BA and VBE segments grafted onto the collagen macromolecules. The resulting structure exhibits enhanced mechanical stability and a three-dimensional porous morphology, suitable for use as scaffolds in regenerative medicine.
