  • Low odour oligomeric photoinitiator and method of making the same
    Patent number: 8022243
    Abstract: Disclosed herein are a class of low odor oligomeric photoinitiators produced from the poly-condensation of dimethyl dicarboxylates and diols of a photo-active moiety. The disclosed oligomeric photoinitiators exhibited comparable photo-curing speed and much lower odor and extractability to its analogue of small molecular weight photoinitiators. Also disclosed are the preparation methods of the photoinitiators, and their applications in photopolymerizable compositions.
