Abstract
A method for the production of a polymer composition comprising photopolymerizing at least one vinyl compound in the presence of at least one photoinitiator, said photoinitiator comprising at least one photosensitizer and at least one reducing agent selected from compounds of formula I and II. Polymerizable materials containing said photoinitiators and said at least one vinyl compound are also disclosed. The polymerizable materials are particularly suited for use as dental materials.
