Performance of Polymer/Carrier Catalysts

By precipitation polymerization polymer/carrier catalysts with different properties were prepared. Table 8.6 gives properties of some samples.

As a test a continuous stirred tank reactor was used. Pressure was adjusted to keep the reactants in the liquid phase (2.0 MPa) and the reactants were fed at temperatures of 60-90 °C at a flow rate of 20 mL/min. The isobutylene concentration was kept constant at 6 mol/L. The methanol concentration was varied from 0.1 to 8.6 mol/L.

Table 8.6 Properties of the prepared and tested polymer/carrier-catalysts. The degree of cross-linking is 7.5% by weight for all samples, balanced with styrene
