Patent ID: 7091254

Claim:
A method for continuously monitoring a photopolymerization reaction in real time by optical pyrometry, said method comprising: providing an apparatus ( 10 ) comprising a housing ( 20 ) having a chamber ( 30 ); a sample mount ( 40 ) disposable within said chamber( 30 ); a light source ( 50 ) for supplying light to induce a photopolymerization reaction in a monomer sample disposed on said sample mount ( 30 ); and an optical pyrometer ( 60 ) attachable to said housing ( 20 ) for measuring temperature of the monomer sample; disposing a sample comprising a photopolymerizable composition within chamber ( 30 ); exposing the sample to light from light source ( 50 ) to induce a photopolymerization reaction in the sample; and monitoring progress of the reaction by measuring temperature of the sample with respect to time.
