摘要：
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 the influence of the reaction temperature on the m and n orders of the reaction and on the phenomenological rate constant k was investigated. Then, a mechanistic 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 Elsevier Science B.V. All rights reserved.
