As shown in Tab.3,G was increased firstly and then decreased with the increase of BP content and was maximized as48.7%at the BP mass fraction of 0.6%.The increase of BP content usually forms a large amount of macromolecular radicals and thus initiates grafting,whereas the too many photoinitiators produce excessive macromolecular and semipinacol radicals,which will encourage radical coupling between semipinacol and growing chain radicals.
