Refractive index changes in polymers bearing pendant active ester groups by thermal rearrangement reaction

Article abstract of DOI:10.1246/cl.2011.1363

Linear and branched polymers bearing S-(2-benzoxazolyl) thioester groups were selectively synthesized by free radical and photoinitiated radical polymerization, respectively, of S-(2-benzoxazolyl)-4-vinylthiobenzoate. Upon heating, the pendant S-(2-benzox
