Radical addition polymerization of acrylates in a Buss-Kneader

The radical addn. co-polymn. of 2-hydroxyethyl methacrylate and Bu acrylate is carried out in a continuously operating Buss-Kneader. To calc. temp. profiles over the length of the kneader the heat balance is solved. For the heat transfer coeff. a model based on the penetration theory is used. This model is exptl. verified. The reaction kinetics of the radical addn. polymn. are studied in a differential scanning calorimeter. The polymn. kinetics are modeled using non-stationary radical concns. The calcd. temp. profiles over the length of the Buss-Kneader are a good approxn. of the exptl. data. [on SciFinder (R)]
