Novel oligomeric photoinitiators were synthesised by reacting benzoin with isophorone diisocyanate-terminated oligomers of dihydroxy-terminated depolymerization products of polyethylene terephthalate (PET). PET was depolymerized by ethylene glycol (EG), hexylene glycol (HG), polyethylene glycol 10 000 (PEG), and α, ω-dihydroxy poly(dimethyl siloxane)s (PDMS). Oligomeric photoinitiators were used as free radical initiators for polymerization of styrene and acrylonitrile. Formation of block copolymers was illustrated by several characterisation methods such as FTIR, 1H-NMR, DSC, and GPC.
