Abstract
The kinetics of photoinitiated polymerization of a dimethacrylate oligomer with 2,2-dimethyl-2-hydroxyacetophenone (Darocur 1173) was studied by using isothermal photocalorimetry. First, an autocatalytic model was used and th e influence of the reaction temperature on the m and n orders of the reacti on and on the phenomenological rate constant k was investigated. Then, a me chanistic model was applied to calculate the k(p) and k(t) rate constants. Their evolution with conversion was studied at 50 degrees C. (C) 1999 Elsev ier Science B.V. All rights reserved.
