Abstract
|
The kinetics of an A2 + B3 system is discussed theoretically with respect to the development of the 7 different structural units and the degree of branching DB. For A2 + B3 systems, the comonomer ratio, the relative rate constants and the process conditions have an influence on the resulting structure as shown by numerical simulations. With increasing A : B ratios f(A/B), the degree of branching DB will be increased. Also the relative reaction rate constants have a strong impact on the distribution of structural units, especially when the reaction rate constants for the pathway of the B3 monomer are changed. In all cases, the conversion is a critical issue to obtain high molecular weight products.<br /><br />General Papers<br />The 226th ACS National Meeting, New York, NY, September 7-11, 2003
